In viewing your pictures you have posted at:
http://www.amazon.ofoto.com/I.jsp?c=xmjvgr.a2slbkd3&x=0&y=-oz7qgi, had some questions.
The slide topper (in pic 1) looks like a good way to keep rain from finding a way into the unit if not parked tilted the correct way. Was this a do-it yourself project? Order of magnitude on price?
Noticed (in pic 5) that you do not appear to have a spare tire under the rear. My 211-S (5.7 Chevy) has a spare with "v" shaped protectors bolted to the frame on either side. Have you done away with your spare or found another creative answer?
Have you found a towel rack that works for you?
