The specific terminology is arbitrary at best and is (I think) often forced upon us by the industry to idicate a change in "class" and therefore the money you should spend.
To get technical a 5th wheel is a travel trailer. Now, before anyone loses their minds, please hear me out. ;) It is a trailer that you travel with, and therefore it is a travel trailer. The 5th wheel name is really only a description of how it is towed. (You'll note that a horse trailer is a horse trailer, although some are in 5th wheel configuration while others are a tow-behind type) The same could be said for the moniker "bumper pull." It really only describes the how, not the what.
When I was growing up we talked about Truck Campers, Tent Campers, Pop-up or folding Campers, even Van campers (Class B conversions). Motorhomes (C and A Class) were all Winnebagos, just as all sofas were Chesterfields.
It's just my $0.02, but to me they are all campers, as are the people in them. Or as my wife said when I suggested we go tent camping with the kids: "I like camping, but I DO have standards." lol
Enjoy!
