Do you always go to the same place and spend the whole time there?
If so look into CG's that have a "Seasonal Section". That way you can park any type or size TT and/or park model if you are sure you won't be travelling anymore.And it becomes its own storage place for the off season.
That section is filled with Seasonal ""RV'ers" no residential folks.
Kills two birds with one stone. You don't have to schlep it back and forth and you can buy what ever size you want. Although you can take it out and use it or home for the off season but your spot will always be yours. Just a different way to look at it.
I'm originally from the IL/WI border and all the CG's I have stayed at that had a seasonal section they all seemed to be having the time of their lives because you can do so many different things around the RV that are permanent that you can't do in a regular CG setting.
