Really ?

I just noticed thumbing thru my owner's manual(2012 Monaco Knight) that it suggested to run the coach at least 20 miles every two weeks.Do some people actually do this if they are camped for extended periods of time,say a month or more?Personally I never have nor have ever seen anyone else do it.Just wondered and am now curios if it hurts the engine to sit for extended periods.I forgot to say I have a Diesel engine.

Diesels do like to be run and don't like to sit, but this seems a bit on the extreme side to me.

I think most DP owners are careful not to just put them in storage for months at a time and ignore them. Probably every two months or so I would try to take mine out for a 20 mile drive just to get everything up to operating temperature... including the tires. I know of nobody who breaks camp every two weeks just to exercise their DP.

BTW, you can add the year, make and model of your coach to your signature line using the "User CP" (control panel) here on the forum. That lets everyone see at a glance what type of rig you're asking questions about.

no engine/drivetrain should sit for extended periods of time,when we go to florida for 3 months I will start the engine and genny every month and let them run for 30 minutes.If I were to stay somewhere for 5-6 months I would break camp to exercise it after a couple of months or so.

I have to disagree: engines are quite happy to be at rest and diesels are happier than most. We don't start the coach engine unless we plan to drive it and don't drive it unless we have somewhere to go.

Transmission and rear axles have some seals that like to be lubricated to stay pliable, so it's nice to drive a bit to circulate fluids in them. However, we don't do that either and everything seems to stay fine. We've had three different coaches (two gas, one doiesel) and routinely park for 2-3 months at a time in summer and the coach sits at our Florida home 4-6 months a year as well. 15 years experience so far.

Do what you think is best, but I wouldn't get in a tizzy over it one way or the other.

Two weeks, no. 4-6wks, we do. But if you do, make it far/long enough to exercise as much of the systems as possible (e.g. trans temp up to operating temp, genny under a modest load, aqua hot (on diesel), etc.). I try to pick "nice" days in the winter time to go for a short drive (a couple of minutes to the Interstate, then 10-15 minutes out and then back). I try to avoid brutally cold days so the Genny doesnt run long before the oil is up to temp (the ISL can be pre-heated via 110v or Aqua Hot).

I have the same MH. I try and run mine at least 20 miles every 2-3 months. Do not just start the engine and let it idle, it's not good for the DPF system.

This was the subject of a thread some months ago. This was my post at that time:

>>>My first year I would exercise the Cat. Then I asked a couple of other volunteers their procedure. They both towed large fivers with road tractors. One had spent an entire career with large diesel vehicles.

It's a two-step process.

Step 1: On arrival, shut off engine.

Step 2: On departure, start engine.<<

Just remember a little warm up and for sure a cool down before you shut it down. That turbo shaft spinning at 15,000+ rpms (higher when the engine is off idle) doesn't like the lack of oil pressure. You may have covered the cool down while checking in to the CG

Have a wonderful day!
