I live in Northern MD 11 mile from the PA line, i leave my camper plugged in all winter and have been doing this for 10 years, i check the battery once a month. By leaving the camper plugged in it keeps the battery on a trickle charge and somewhat warm, but the battery water level needs to be at a normal level. I never had a battery go dry during the winter by leaving it plug in and if water is need it, it is best to add water to a warm or fully charged battery.

I take mine out and leave it in the garage and then charge it once a month or so to maintain the battery. I have to blow the snow out of the driveway and snow blowers and electrical cords don't mix!! My parents leave theirs plugged in due to its location in the back yard. Either way doesn't matter.

My RV's have been plugged in since 1977 with no issues except maybe a bit higher electric bill.

Plugged in all winter. Since everything is off except for Converter and CO detector, its not too expensive.

I've been leaving mine plugged in. I have a floor model electric heater inside. I set the gas trailer heater on the lowest setting so if power is lost for an extended time and I'm not home, the trailer gas heater kicks on at 55.

I leave ours plugged in. The only exception is that I don't winterize, so I have a ceramic heater in the middle of the TT. No problems.

Whether you should leave your Sunseeker plugged in all winter has a lot to do with what type of converter you have.

2 stage way.

3 stage converter.......yes way.

Many of the posters here have trailers. Most trailers come with 3 stage converters. Many motor homes only have 2 stage converters. In that case, don't leave it plugged could boil your battery dry.

Check out the make and model of your converter and see what you have. Even if you have a 3 stage converter, still check the battery water level every couple of weeks as a precaution.

I bought my RV (motorhome) from a previous owner who always left the RV plugged (year-round). When I got the RV home, one of the two batteries was dry as a bone, the other battery was still okay. Since mine has a 2-stage charger, I have to agree with MTNGUY above, until I can upgrade my converter, I won't leave it plugged in. I removed the battery to my garage and monitor it monthly.
