I have had the TT in my garage doing a few mods getting ready for the upcoming season.
I converted the rear closet into a pantry last year, it has been dark and hard to find stuff in the pantry so I added a light.
There was a light in the hall so I picked the power up from there.
I also added some racks to the door of my pantry
When I had my dinette apart last year I notice how small the drawer was compared to the space available under the seat.
I was able to make new sides and bottom for the drawer and make it 6" longer.
I also added a few hooks to hang jackets on.
The TT is cleaned and ready to go. Waiting for it to get a little warmer before I do the water system tho.
