The first thing I did was build a 5" fold down step in the bathroom so my feet doesn't dangle while on the toilet. Installed 6 LED map/reading lights, 2 in the cockpit, 2 in the bedroom, and 2 above the couch which I replaced with a reclining love seat. Installed a sound bar because the volume is weak when playing a movie. Put above dash speaker on the dash. put in more electrical plugs. Purchased a dash cover and a outside windshield cover from prompt.com. This one does not require drilling holes. Vent covers and a Max Air in the living room. Outside propane connection and a few other things. If you want more info or photos just let me know.
