There is a whole heap of difference between a 32 & a 40' besides that 8' of length which will stop you from getting into a bunch of campground sites that you would like to visit.
There is the weight & the truck needed to pull stop it. 40' is fine if it is going to sit as a seasonal somewhere but if the plans are to do some real traveling smaller is much better.
"The very first trip we took was to South Dakota. I stopped in Cheyenne to refuel and weigh the rig. Came in just under 19,000 pounds, including the truck of course." Ummm, you wanna check your weights again? Sounds more like a trailer only weight.
