Silver color (love) Put a starboard plate 12"x12" on the rear bumper attached to the ladder to hold my tent, also cargo box on top of bumper attached to slide in hitch. A plate attached to the ladder rungs to hold a spare tire or bike. Also a 5"x5"x24" pvc tube fastened underneath the frame by the sliding door to hold the tire jack. I am going to recommend the waterproof holder to Winniebago
Interior
I added a smaller table top onto one of the pedestals. Put a pull shade on the fan overhead. Shoe holders on the side of the bed. I put the tire air inflator under the front passenger seat area. Took off the screws under the toilet box to put in chemicals and the sewer hose with gloves and cleaner. I am going to recommend this to Winniebago. Added a high heat and pot holder rack to sit on the kitchen counter top. Also a thick rubber outdoor map under the shower drain to pull out quickly and doubles as a level block.
Customizations
Added a inside temp sensor (app) and cheap thermometer for my pets. Added a tire pressure and heat sensor for all 4 tires. Put in lists on 3"x5" cards into visor for things to handle and have on hand.
