I have seen many showhaulers and they are nice units. We build coaches - one at a time for specific clients - in Minnesota (not Indiana) and our prices seem to be about 30-40% less than most of the large manufacturers. You can see our work on the link below and check out the progress pics of our latest in the Coach in the Making section.
I agree with the earlier post about 85mph. When the turbo starts to sing the speed grows so that you can't even tell its happening and before you know it you are going that fast. We have pulled our race trailer behind and didn't even know it was there.
Due to demand we have started to design coaches that can be built by other shops and that has been fun for us. I'm an architect by training and profession and I think we build the only architect designed motorhomes in the US. Airstream has an architect on retainer for the CCD line but to the best of my knowlege no other architects are designing motorhomes.
I'd love to design or build a coach for you.
