Personally, I think this is a good choice. I use 4wd with the camper way more often than I use it without the TT.
#1 spot, our drive way, 10% grade, concrete. Drop it in 4L, and all I do is apply brake, no throttle and guide it back. Have stayed in CGs, that have beautiful grassy sites, (no gravel). Wet grass plus the TT, 2WD you just spin. Also have used it to back into campsites on nice gravel pads, up a hill, and in 2WD, you just spin, not in 4wd.
No way, would I buy another TV that is not 4wd.
