Newbie looking for info

I am researching in order to purchase a class A motor home. We will be full timing and workamping. I am trying to decide between gas and diesel I have heard that a diesel that sits for some time may have problems with leaking seals and so forth. We may be parked for a month or two at a time and want to know if this is a real concern. Do other people run your diesel on a weekly basis or not worry about it.

  • I just went through the same decision making. I chose a new 37ft gas unit. I'm retired so I move slowly and stay about a month when we stop. I know I will move a little slower up the mountains but that's ok with me. I have friends with DP's and I know they spend a lot on initial cost and maintenance. Everyone is right when they say they are quieter, ride smoother, maybe get better mileage, but when we are stopped I can't tell the the difference. In today's gas units they have more power then the old 454 ci engines and they have more storage outside. You have to decide what fits your needs, floor plans, and what fits comfortable in your budget. Good luck with your search.

    Shhh!...don't tell that to the farmers who leave their equipment sit all winter without ever starting them.....:W

    A month or two won't hurt a diesel. What will is if you start them for short periods of time and/or let them idle. If you are going to 'exercize' them, take them out for about a 30-45 minute drive to warm everything up. If we are sitting for any length of time, I simply bundle her up and let her sit. Exercise the genset with a load monthly, cover your tires or use Aerospace 303, and you're free to enjoy life. Make sure your fuel tank is full so condensation doesn't form inside the tank. When ready to hit the road again, add a bottle of Diesel 911 or similar to the fuel tank, put in your Willie Nelson CD, and you're "On the Road Again".....:B...Dennis
  • If full timing the diesel will be the only way to go as it will have more storage room to put all your "stuff"
  • A month or two, particularly in a dry climate is not an issue.

    Do NOT start the engine unless you can drive at least 25 highway miles-- long enough to get the OIL (not just coolant) up to operating temperature.
