As you have noted they is a big difference between camping and RVing. Each has a definite time and place.
When we purchased our TT, I told my wife we are keeping the PUP. There are times when I just do not need the conveniences and hassle the TT affords.
I really like 15 mpg vs. 10 mpg, the ease of backing into a camping space and pulling it through the fast food drive thrus.
Yes I have packed wet, had the wind flip the awning over while the entire unit was shaking, and it takes a while to set up. It is also true I like the big bathroom and pantry in the TT. But hey, it is camping and I like that also.
