Very sorry that I am seemingly argumentative--not sure which state parks you are referring to. Down here in TX, there are lots of parks with lots of space; in CO, same deal. We have camped for years in state/natl forest cgs without hookups and have found them to have plenty of room
I completely agree with the floor plan being part of the camping experience--sounds like you may be kind of tall, which is a problem in itself to solve without $$$. Since I am vertically challenged, every trailer I have ever had, came with lots of headroom.
If my first purchase had been a fiver, don't know how that would have worked out.
