So, here's the deal. I thought of selling my SA due to family issues but have resolved everything and am keeping her for the time being, 1 year or more, we'll see.

2013 SA450, 180ish hours.
Has the aftermarket surf system
rear locker bags are upgraded to 800lbs
Z5 cargo bimini
S bend tower
snap out miners moss flooring
6 in boat polk speakers
4 polk tower speakers
aftermarket sub
two batteries on switch
battery tender
underwater LED's

Basically fully loaded as most Supras are. I'm looking for some ideas. Things I've thought of

hot cold shower
docking lights, not sure how to add with pickle fork
LED speaker rings, cup holders
zone control for stereo

Trailer is two tone and has the runway lights, saw a centurion that had a trailer light shining the centurion logo on the ground behind the boat, thought that was cool, maybe do the same with Supra logo.

not interested in replacing speakers or the stereo so please exclude those options.

Ready.... Go! Thanks for the help and ideas.
