Restart after 3 months

Recommended Posts

We have a 2014 Tiffin Allegro DP with a Cummins 340 HP engine and an Allison 2500 transmission. We are looking into a 3 month Workamping assignment. After sitting for that long what is the proper/recommended  start-up procedure for the engine/transmission. We will be living in the motorhome during the assignment.

I just parked our coach in its winter parking location behind our barn. It will stay there until I bring it out in early March. Most likely I'll do like past years and not start/run the engine during that time. Of course, I've done all the usual prep including changing fluids, checking condition of antifreeze, etc. I also make certain that all air tanks are properly drained so that moisture doesn't sit in them for months.

Doesn't seem like you should have problems starting your engine after a few months idle time. My thought would be to do similar to what I will: check all fluid levels, check condition of air cleaner, and do a visual inspection. If you can crank the engine without starting it, do that for a few seconds first to help circulate the oil. If you can't do this, then avoid running above idle until oil pressure comes up after starting.

Of course, if your manual has anything specific about storage and bringing out of storage, that would be the primary route to go.

Just a short comment .

We are a Gas motor home, BUT I believe gas and  DP would have these same concerns. Question how to maintain the Fuel additives  etc.

Since the chassis battery's need to be maintain with a charger of some kind.

As I believe the coach ? does not keep them charge up in them when plug to AC.

Just my two cents

Gas is slightly different, but mostly the same. My experience is that gasoline does less well in storage than diesel, especially modern gasoline with all the odd ingredients in it. I'd check with one of the fuel gurus about the best additives for that, particular to your locale (for moisture, temp, & the specific type of fuel mixture pumped in your area).

My coach has separate house and chassis battery chargers, and as long as both are turned on I'm good. This could be done with any coach for not much money, and there are many options for keeping the chassis batteries charged from a single house battery charger. The Xantrex Echo Charger is one option. What you don't want to do is just plug in a cheap (dumb) charger and let it run unattended - they typically can boil your battery dry over time.

If the chassis batteries are fully charged, the simplest method for keeping them for a few months is to simply disconnect them, usually by way of pulling the negative battery terminal which connects the battery bank to the chassis/ground connection. Depending on the particular setup, it might be necessary to pull multiple ground cable to accomplish this. Label everything and take photos first.

Even in extreme cold, a fully charged battery will not freeze. However, if the battery is going to be left disconnected through a stretch of very cold weather it's a good idea to check the state of charge and/or connect a charger from time to time to ensure full charge.
