Trailer Hitch Boxes

Hi got a SanteFe 12ft in fairshape paneling has a bit of water damage, real wood cabinets need refinish, carpet scraps r floor, outside white paint (spray) looks 75% good. 2 sm broken window vent glass, couple "dents" roof metal. Unfinished toilet closet (with a toilet)

few orange and red turn signals etc are old, faded, broken etc . should I get LEDs at walmart?

Hitch is "too low" for bumper ball (other thread).
I "want to"
a. Replace curtains
b. remove cabinets, remove all or most paneling, check for mold, insulate siding, get new paneling perhaps varnished 3/16 luan c. put a boxing glove on a broom stick and punch the ceiling to get rid of dents d. Rmv rear bumper to save wt e. polish of wh spray paint to shiney Al finish f. Rewire and use LED signals. WHAT DO YOU THINK OF MY PSEUDO RESTORATION? Any "do's and don'ts" I should know? Thank you, Bill.
