One reason why we didn't buy a Vegas was the puny size of those wheels. If they had one set up like gmtech16450yz, we might have a Vegas instead of a Windsport.
I have been looking desirably at the longer motor homes that use 22.5 inch wheels like we had on our diesel pusher. I'd love to be able to change the wheels on the Windsport to 22.5 the inch size.
I understand the situation when doing things outside the box. I have been riding motorcycles on the "darkside" (car tire on the back) for ten years and have been the subject of many unkind remarks and predictions of disaster. I am still in one piece and so are my motorcycles.
