Tow and go to a permanent site

Don't leave the black valve open all the time. :)

The only thing I can think of, if you have been towing for years and now going to sit for a while, you have an opportunity to stabilize your camper more so it won't rock so much. You can put blocks under it or bottle jacks because you won't have to moving it now. The permanently park camper's I've seen all my life, folks make things more stationary, and the "mobility" of the camper seems to become less "mobile". No problem parking, but if you decide to take it on the road again after a couple years, you'll need to check out all the moving parts with a fine tooth comb again.

We were towing for abt 15 years and finally landed at a seasonal site about an hour from home. It works out well whereas kids sports and other commitments do not keep us from camping. I have a type of site where I can pull out anytime and I do not keep it there for the winter months. I bring it home.
I have fixed up the site nice and am at a campground that I have been going to since the beginning.
All we do is pack laundry and stop for groceries. As mentioned, Sundays are great. Just load dirty laundry take garbage and go home.
This has allowed us to camp every weekend the past 2 seasons.

What is it that you are looking for? We were seasonal campers for 11 years. Have a trailer placed and set up on site. Campground was open May to Oct. the trailer was on blocks, we used PVC pipe foe the sewer line, had a shed, golf cart etc. We had the maintain the site but we could place leaves and pine needle piles on the edge of the road and they would be picked up. We had a lot of fun camping like this, you learn to love Sunday's as you don't have to pack up.

We have picked out a new place for if I can no long tow but hopefully that will not be for awhile.
