We bought a 2012 23B this past winter. We have had it out a few times, it pulls like a dream, my truck just feels like I have a heavy load in the bed.
I have two modifications I would recommend. Remove the drawer under the dinette. I attached the original face plate to a piano hinge for a nice interior access and removed all the protective paneling. It makes for a very nice front cargo hold
The second mod, add shelves to second wardrobe cabinet. I used metal linen shelving. We each (3 of us) have a shelf for our cloths and one more for towels.
I will probably take some pics and post them this next week (she is in for some warranty work right now
You will love the TT.
