Welcome to FRF, from another 2016 TracerAir 255 owner!
Our upgrades are:
For dry camping-
a small inverter for running the tv.
Honda 2000i inverter generator.
LED bulbs for all the lights.
15 gallon tote tank.
6 gallon water jug.
Inside-
Mattress topper.
Wire shelves in pantry and bathroom sink cabinet.
Larger 32" smart tv in living area.
19" smart tv in bedroom.
Plastic storage containers with drawers in bedroom.
Ceramic heater when we have hookups.
Oxygenics Body Spa showerhead.
Outside-
Electric tongue jack.
That's all I can think of right now. PM me if you have any questions. We had a number of warranty issues but they were all fixed by the dealer.
By the way, we are also retired and have been spending time in Arizona and just got back from there.
