Diesel versus Gas

So I've seen numerous posts on this site over the past month that state if your rig is going to sit for long periods of time, go with a gasser. Why is this? Are the seals different in the engine?

I'm trying to decide between a gas and diesel for my next unit, and am leaning towards a diesel just because I'd like the higher quality interior, air ride, and having the engine noise 30+ feet behind me. I use my rig about 4-5 times a year, sometimes for a weekend, sometimes for a couple weeks of travel.

Thanks in advance for any advice.

  • I have not even picked up my Diesel pusher yet.
    But, I know some of Diesels and have done some homework.
    Diesels will have more resale. Not many V10 RV'S with 100000 miles out there.
    Diesels CAN have better interiors because of weight.
    Diesels WILL have a better chassis.
    Diesels fuel will not go bad. It will get algee in it and the cetane will go down over time, but it will start if the fuel system is air tight.
    Diesels WILL pull much better over all and better MPG.

    I am at the lower level of Diesel Pushers, but in my opion, I would buy a diesel 3 to 4 years older from a gas for the same money.

    BTY, Do you know what the inventor , Diesel, based the fuel of the diesel motor on? Vegetable oils. If you are using a pre 1998 motor, you can use WVO, TRASN FLUID, MOTOR OIL, .....almost any oil to run you rig. The newer ones uses injectors and pumps that have a hard time with the thicker fuel, but heater will help that too.

    A diesel engine can set for 5-10 years and crank right up with a new battery. Not going to do that with a gas engine. This is even before the sorry gas they are making today.
    OP, under 36' you do not need a diesel, but like you said... "the higher quality interior, air ride, and having the engine noise 30+ feet behind" plus a turbo and an exhaust brake.

    I believe they were suggesting that if you are not going to be using the coach it's not worth the extra cost in buying a DP. Nothing to do with anything engine related.


    Ahhh, maybe that is what they were talking about. I was thinking that somehow gassers fared better sitting for long periods of time. I'm looking at turn-of-the-millinnium diesels so depreciation won't be as bad as on a new one.

    I use mine the same way. For me it was a better ride,air brakes,exhaust brake and zero engine noise. Letting either sit has the same affect.
  • the most noise I had in my As was with the old P-30/32 chassis when that sucker would drop down a gear under a hill climb. sounded like a jet taxiing.
    bumpy
  • I never found the engine noise to be that bad in my Gas A's.
    As for interior. There are some gasses that are just as nice if not nicer than some DP's I have looked at.
    How long do you plan to keep the MH?
    Some of us just have higher standard's.
    For us it was $$ and use.
    Another reason we down sized from an A.
  • I've had three diesels, a 2001 F-250, a 2012 F-350, and now a 215 F-350. You won't have any problem with them setting. Make sure sure you derail the fuel separator. My truck will,pull anything you can hook it to. This especially important if you plan to travel out West in the Rockies. Make sure you have an engine exhaust brake( works in tow-haul in Fords.
    Happy Trails.
  • If diesel is what you want than go diesel, its what makes you happy, as for me gas works fine and cost less to maintain..

    Remember the more the RV cost the more you will pay in insurance and license fees..
