We keep our rig in storage where we can access it year around. We usually take it out once a month, or at least drive her to the local fish and chips house, then to the lake to have lunch while running the generator. This also lubricates the seals and cleans the rust off the brakes.
Now, if we really have to get away and stay in Ohio... The state park lodges usually have specials we take advantage of. We are retired, so we can go midweek and use that advantage. But, the specials are still good on the weekends. We find that a two or three night stay can cost only a little more than taking the rig and paying for a campsite.
These work for us. I do not know your situation, so for you, maybe not so much.
Tight lines!
