Is sitting for four months detrimental to a MH?

From January to April, I volunteer for a festival (I mainly do IT/computer work, so it is nice to take a rest from that on occasion.)

I'm eventually going to pick up a class "C" motorhome once my existing tow vehicle and trailer are paid off, later this year, and plan to use the trailer as a down payment on a short class "C".

The issue I'm looking at is making a campsite, where the motorhome gets parked in January, left on the same spot until April. Normally, it will reside in a driveway and used constantly, but for a quarter of the year, it will reside in one place, and used on weekends.

During that time, I can't really move it, as there is limited camping space, and if I go out even for a few hours in it, there is a good chance I might come back to find my spot taken up by a latecomer's tent or trailer, so it pretty much has to stay put due to that.

Will this hurt things, long term, by having it sit in one place and not driven for four months? Other mechanisms like the generator and such would be definitely used on weekends, and the vehicle's fuel tank would definitely remain near full with Star-Tron used for a fuel additive, so bad gas is kept to a minimum. I also use full synthetic as a habit with all my vehicles (and generators) because it can sit longer without breaking down. It goes without saying that before and after sitting, the oil gets changed.

Most likely, the MH will have auto leveling jacks (which will be placed on large jack pads due to the sandy soil.) Are there any issues with keeping those down for this length of time, or should they remain up, and I make sure the vehicle is level by using planks with the tires, and not use the jacks at all?

My goal is to have this MH for two main purposes... the festival season where it stays put, and the rest of the year where it winds up used as a secondary vehicle, going out of town on weekends.

  • All this advice is reassuring. My travel trailer aged more in the past year, where real life caused me not to be able to do monthly upkeep on it, than it did in the preceding five years. So, for me, the worst enemy for a RV is letting it sit.
  • Won't hurt 'em. Most people up north do it every winter.
  • Thousands, likely tens of thousands, of motorhomes site for longer every year. Not a problem as long as you follow basic maintenance guidelines above.

    One thing I was not prepared for with full-timing and volunteering for months at a time was the sewer hose. I know to cover my tires and protect external plastic parts as much as possible from UV damage. Didn't think about the sewer hose sitting out in the sun every day for months. It does get damage from UV and might lose flexibility along with developing cracks on the top side.
  • I definitely plan to add a solar system (hopefully 250 watts minimum, likely more, depending on roof space.) This, plus an Amp-L-Start should take care of the batteries.

    I also am going to see about an Onan EC-30 (not the "W" model, that was discountinued, but the wired one) so if the house batteries get below 60% SoC, the generator fires up for a few hours. Similar with a genset run for an hour or two every few days before quiet time. This will keep the batteries from being dead, while I'm gone.

    The tire covers are a good idea. I should see about that as well.
  • Add a modest solar system and you will be golden.

    The only thing I might do extra is cover the tires if they are in direct sunlight.
  • I think sitting unused tends to inflict some wear on machines but I wouldn't worry about it. When mine sits I start it up once every couple of weeks and occasionally take it out and drive around. I check the status of the batteries and plug it in to bring up to full charge and I run the generator with some load on it about as often.
  • Ours sits from October to April each year. I store indoors. I plug it in when I arrive, let charge up some, starts right up. Spend a day or less getting things operating again. Flush out winterzer, inflate tires, run gen set, heaters, ac, ice maker, filters, etc. Ready to roll.

    x3 that it should not be a problem. Up here where we have this thing called "winter" many, many people leave their motorhomes sitting unmoved for a few months every year.

    If you don't have them, I would highly suggest getting vent covers for at least one or two of the vents and leaving them cracked open slightly while it's parked to give some ventilation. Vent covers are just generally really great things to have. As a trailer owner, that's probably all old hat to you anyhow.
  • our rig sits for three to four month a couple times a year, but it's in our backyard, so we're in and out of it frequently, but if you're closing it for 5 days at a time, you might run a dehumidifier and a fan to circulate the air, etc.
  • Not at all. If you don't have electrical hookup you'll need to disconnect the batteries or charge every weekend. Shut the power & water down when gone. You could do solar depending on how many batteries you have.Keep battery fluids full.

    Ours sits for 6-7 months every winter, plugged into power.Just add a fuel stabilizer.Being in Texas you might want to add some water collectors to keep the humidity out of the coach.
