We repainted the brown stripe and it looks a whole lot better now. I am gonna try some CLR on the black streaks, someone on the motorhome forums claimed that is the only stuff that ever worked for him. I also started repainting the whole interior as well.
Also, I decided on a mild remodel of the rear section, with integrated computer, D9200 monitor, Mame control panel, audio stuff, printer, scanner, etc. Gonna make it the entertainment section and move the small TV into the front area of the RV. Might end up using the middle bed as my bed, tested the big drop down bunk in front and I think I am a bit heavy for it (wood made stress sounds).
So, all my games and a nice empty woodgrain cab are for sale. I posted prices in buy/sell/trade.
