Which model did you get? We are looking at adding 12v and usb charge outlets to ours, also making drawers for under dinette seats since ours did not come with them.
Another feature I saw in some TT were cubby holes at the head of the front bed, I'm thinking of adding those.
We plan on using the first couple times out to decide what we really want in it.
