gas milage..

I started looking at diesel, but quit because they are
hard to find, and when you do, they are much more expensive.

I am looking at RVs from the 1990s to early 2000s.

At some point along this line, they went fuel injected?
Or by the 90s were the already fuel injected...

Also, new engines now have the spark coils for each plug
rather than one coil and distributor.

Then, I have been seeing RVs with "lite" in the name. Is this
referring to fuel economy?

Is there such little difference, that I shouldn't consider mpg?
Or is this a significant feature to alter my purchase decision?

    Diesels have been injected as far back as I'm aware of. The reason to buy a diesel is you are towing very heavy loads. Unless you are towing 40,000+ miles per year, no way you will pay for the diesel in fuel savings (with the current prices, you don't save anything)

    Did you switch over to gas engines halfway thru? No diesel has coils or plugs.

    Lite is a marketing term more than anything. Many "Lite" RV's aren't paticulalarly lite and even the when they are, it's wind resistance that really kills the MPG.

    As others have said figure 8-10mpg or expect to be disapointed.

    Yep, that's what towing a TT will get you.
    motorhomes slightly less.

    Don't think that RV'ing is cheaper than a regular home. It's a lifestyle, not a money saver.

    if a Ford chassis, get one of the 1999 or newer chassis with 19 inch wheels. if chevy be sure it isn't just a rebranded P-30/32, get one that has been improved.

    I have a Class C on the Chevy chassis. I get about 9 mpg towing a car. The Ford chassis gets a little less MPG. If you are thinking of a travel trailer or a 5th wheel, it depends on the weight and aerodynamics.

    The lite RVs probably get a little better gas mileage but may be lighter for a reason, not as well built.

    AFAIK, newer RVs and tow vehicles do get a little better gas mileage but unless you are getting a small Class B, none of them have good gas mileage..
