When we had our TT, I would disconnect shore power in the winter, remove the battery and put it in the garage with a battery tender attached. I’d winterize the water system, clean out the fridge and leave the doors open, then cover the TT until spring. No maintenance required.
Now that we have a motorhome, I’m debating about leaving shore power hooked up all winter or just put battery tenders on the house and chassis batteries. Everything else ( water system, fridge and covering) would be the same.
There are advantages to both approaches.
My questions are;
Since I should “exercise” the genny, and probably start the engine periodically, does it make any difference which approach I take?
Would it be reasonably safe, to leave a small electric space heater running inside the covered motorhome to keep moisture out? (In that case, shore power would be necessary)
Am I risking shortening the life of the converter by leaving shore power on an unused RV all winter?
Thanks for any input.
