Congradulations, Warpath, on the new rig. From my experience, the one thing that I did not have problems with was the truck. I have an '03 Columbia with the Mercedes and 12 speed freedom transmission. Knock wood, it's been 2yrs, 2 months and 44,000 miles. I saw the pics of your truck. Take a look at my post at conversions-general, height/length issues. Let me know when you damage the bottoms of those back doors. I bet you won't be able to go more than a few months before you have to go down a driveway and over a crowned street and drag the back end. I'm not wishing you bad luck. I'm simply trying to call attention to a situation that should be remedied while the conversion is still on paper. Good luck, maybe you'll have different fortune than myself or the conversions that I've seen on the road for a while. The same door manufacturer that Showhauler uses now has a design for a rear door that is tapered so that you can get some air between the asphalt and aluminum.
