We originally started out with a 34' TT bunk house and lasted one season. Kids complained of no room. Wife complained of low ceilings. Went and bought a 40' bunk house 5er with double slides in the rear bunk house. Kids loved it as they had their own room to play in when they couldn't be outside and had their own bathroom. Wife loved the ceiling heights and all the extra space. I liked it as it towed 100% better than TT.
As for parks we haven't had any real issues. Just that we usually have to park the truck in a different spot because it doesn't fit on the sight.
We kept that one for two years and just upgraded again. Wife's choice again.
