Page 17: Fuels For The Motor Home
TIFFIN MOTORHOMES –ALLEGRO® Chapter 2 DRIVING & SAFETY INSTRUCTIONS • Do not operate the cruise-control function during any extreme weather situations (e.g., snow, ice, sleet, heavy rain) or when road conditions are hazardous (icy, snowy, winding roads, city traffic) or when a constant speed of the motor home is not possible or if traffic conditions don’t warrant such.
Page 18: Liquid Propane (Lp) Gas System
TIFFIN MOTORHOMES –ALLEGRO® Chapter 2 DRIVING & SAFETY INSTRUCTIONS • NEVER use an open flame to test for LP gas leaks or to examine the fluid levels in the fuel tanks. • After filling any LP system, immediately replace and secure all protective covers and caps.
Page 19: Lp Gas Regulator
TIFFIN MOTORHOMES –ALLEGRO® Chapter 2 DRIVING & SAFETY INSTRUCTIONS Generally, loose fittings can be tightened (with “non-sparking” tools) to stop the leaks. If this process doesn’t work, then one must shut off the main gas valve at the LP cylinder(s) and immediately consult an authorized service technician to determine what repairs are necessary.
Page 20: Recommended Precautionary Practices
As with any enclosed system containing the three required conditions for fire (i.e., combustible materials, oxygen, ignition sources), there will exist the possibility of fire. Tiffin Motorhomes has taken every precaution and design practice to minimize or negate this possibility, but the final determination rests with the owner and user of the motor home.
Page 21: Smoke Detector
TIFFIN MOTORHOMES –ALLEGRO® Chapter 2 DRIVING & SAFETY INSTRUCTIONS Do not test a fire extinguisher by partially discharging the unit—this will cause a loss of pressure and may lodge some fire-retardant materials in the valve mechanism and cause the extinguisher to continue to vent slowly down to zero pressure.

TIFFIN MOTORHOMES –ALLEGRO® Chapter 3 HEATING & AIR CONDITIONING Furnace Warning Never attempt to modify the furnace. To do so may cause fire, explosion, carbon monoxide poisoning, and/or asphyxiation. If the furnace is malfunctioning, immediately shut the unit “off” and call a trained service technician to make necessary repairs as soon as possible.
Page 25: Air-Conditioning System
TIFFIN MOTORHOMES –ALLEGRO® Chapter 3 HEATING & AIR CONDITIONING Warning Be cautious when washing the exterior of the motor home; water should never be sprayed directly into the furnace vent. Should any water be forced beyond the rain baffles into the furnace vent, the furnace may rust which, in turn, may cause improper combustion and produce unwanted by-products of combustion.
Page 26: Liquid Propane (Lp) Tank
TIFFIN MOTORHOMES –ALLEGRO® Chapter 3 HEATING & AIR CONDITIONING To cool the motor home, the thermostat inside the Allegro is used—this is the same thermostat which controls the furnace functions (described earlier). The air-conditioned, cooled air is emitted through the vents which are located in the roof throughout the entire coach.
Page 27: Lp Tank Filling Practices
TIFFIN MOTORHOMES –ALLEGRO® Chapter 3 HEATING & AIR CONDITIONING The major component of the LP gas supply is a manifold pipe which runs lengthwise underneath the motor home floor. From this manifold, the various gas appliances are connected by copper tubing with flared fittings so that connections and disconnections can readily be made, as needed.
Page 28: Carbon Monoxide/Lp Gas Detector
TIFFIN MOTORHOMES –ALLEGRO® Chapter 3 HEATING & AIR CONDITIONING LP Gas Regulator As noted earlier, the LP gas regulator (Figure 3-8) is the “heart” of the LP gas distribution system. This regulator reduces and controls the pressure of the gas on the outlet end to provide a constant supply of gas at a constant pressure to the gas-operated appliances.

Follow correct rotation patterns Tire Repair The proper repair of a punctured tire requires a plug for the hole and a patch for the area inside the tire surrounds the puncture hole.
Page 102 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Information on Passenger Vehicle Tires Please refer to the diagram below. P—The “P” indicates the tire is for passenger vehicles. NOTE: Passenger car tires are not recommended for use on trailers, because the capacity ratings are not marked on the side walls of these tires. In the event a passenger car tire is used, the capacity must be de-rated by 10%.
Page 103 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Speed Rating—The speed rating denotes the speed at which a tire is designed to be driven for extended periods of time. The ratings range from 99 miles per hour (mph) to 186 mph. These ratings are listed below.
Page 104 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Additional Information on Light Truck Tires Please refer to the diagram below. Tires for light trucks have other markings besides those found on the sidewalls of passenger tires. LT—The “LT” indicates the tire is for light trucks or trailers.
Page 105 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE The certification label will indicate the vehicle’s gross vehicle weight rating (GVWR). This is the most weight the fully loaded vehicle can weight. It will also provide the gross axle weight rating (GAWR). This is the most a particular axle can weigh.
Page 106 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE It is the air pressure that enables a tire to support the load, so proper inflation is critical. Since RVs can be configured and loaded in many ways, air pressures must be determined from actual loads (determined by weighing) and taken from the load and inflation tables provided by the tire manufacturer.
Page 107 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE 4. The resulting figure equals the available amount of cargo and luggage capacity. For example, if the “XXX” equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage capacity is 650 lbs.
Page 108 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Extra load tire—A tire designed to operate at higher loads and at higher inflation pressures than the corresponding standard tire. Groove—The space between two adjacent tread ribs. Gross Vehicle Weight Rating (GVWR)—The maximum permissible weight of this fully loaded motorhome.
Page 109 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Occupant distribution—The distribution of occupants in a vehicle as specified in the third column of Table I of 49 CFR 571.110. Open splice—Any parting at any junction of tread, sidewall, or innerliner that extends to cord material.
Page 110: Tire Pressure
TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Sidewall—That portion of a tire between the tread and bead. Sidewall separation—The parting of the rubber compound from the cord material in the sidewall. Test rim—The rim on which a tire is fitted for testing, and may be any rim listed as appropriate for use with that tire.
Page 111 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Additionally, underinflated tires will also cause poor handling of the motor home, rapid and/or irregular tire wear, and an increase in rolling resistance of the motor home which, in turn, produces a decrease in fuel economy of operation.
Page 112 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE In certain states, the Highway Patrol routinely weighs motor homes to check for overloaded axle weights. Therefore, there are many good reasons for assuring that the motor home is properly loaded and not overloaded—this can be accomplished through a proper weighing of the fully loaded motor home.
Page 113 TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE More detailed information can be found in the manufacturer’s literature associated with the chassis and/or the tires provided with the motor home. For example, the following table (Figure 13-9) illustrates the inflation pressures for Michelin tires as a function of the loads per position for a specified speed of the motor home.

Also act quickly when anything is spilled or dropped onto the carpet to prevent or minimize staining. Included in the Tiffin Motorhomes Owner’s Information Package is the carpet manufacturer’s Carpet Care Guide. The Carpet Care Guide lists detailed information on cleaning soiled areas and removing stains from the carpet installed in the vehicle.
Page 115: Fabrics
Some stains or soils are extremely difficult or impossible to be removed completely. These stains should receive immediate, professional attention. Spills, spots, stains, or soiled areas are the responsibility of the owner and are not covered by Tiffin Motorhomes Limited Warranty. Warning When cleaning the upholstery and fabric of the motor home, do not use lacquer thinner, nail polish remover, laundry soaps, or bleach.

The mop should be damp, but not dripping. To remove candle wax or chewing gum, carefully scrape off when the material has hardened. For further tips, please see the manufacturer’s information sheet in your Tiffin Motorhomes Owners Information Package.
Page 117: Countertops
TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE Countertops To care properly for the countertops (Figure 13-15) in your new vehicle, always use a heat pad or trivet to protect the surface from hot objects that may mar or damage the countertop surface. Hot pans and heat-producing appliances (such as electric skillets), when set directly on top of the countertop, can possibly mar the beauty and finish of the product.
Page 118: Condensation
Always follow the chassis maintenance guidelines found in the chassis manufacturer’s owner’s manual. All routine maintenance is the responsibility of the owner and is not covered by the Tiffin Motorhomes Limited Warranty. Use the maintenance record found in Chapter 15 to record all performed maintenance as required.
