Been busy adding more mods as we go along:
# 1 - added front speakers per Thor Forums - View Single Post - Adding front speakers to the ACE
They made a big difference, very happy with them.
#2 - installed a combo lighter/USB power block so i could get a flexi light on the jack panel and power the fan- got this one at an auto parts store
#3 - installed decent folding cup holders for driver and passenger sides, Much better than stock cup holders - got these at West Marine
also replaced the stock showerhead with an Oxygenics unit - well worth the investment!
