Verlyn, I laugh at almost every rv park that I stop, when a neighbor will ask what diesel I have. Yes the new tail gate sure gives that impression. I wanted the 3921 model, but they would not put in a washer and dryer in the garage of the 3921, due to the full wall slide weight. So I opted for the 3920 and was able to get one of the last new ones, just last year before they changed to 3921.
I run all around the western states with a large smoker, and compete in BBQ cook offs. There is still just enough room in the garage for my honda 150 and a chest freezer.
See you down the road, Thirsty.
