To further expand on my earlier post:
I have been a Dry camper/wanderer most of my years and since having kids and more toys, a seasonal site has actually tripled the amount of days I have gone camping. There is no way I can fully enjoy a camping trip anymore without a seasonal because I would have to leave stuff at home. I can't take 3 atv's, fishing boat and a 30ft TT with me on everytrip. Now once my boys are older and on their own I can go back to dry camping and leave the seasonal behind.
I did 3 trips with the same TT I parked at the seasonal site last year, just hooked up and left, simple as that.
As a side note:
I thought you had to use a TT to find out what was gonna break, not just towing it around accumulating mileage. If you never used the fridge in 40000 miles how would you know if it worked. Plus a TT parked is less likely to leak then one that has been bounced around for 40000 miles
