I am 6’8”. I cannot speak to the older style R29, but we purchased the newer style. One of the main drivers of our decision, is that I fit as well as can be expected. One selling point, is that the bed is long enough! I can stand in the forward portion of the cabin, and don’t have to bend down too much in the galley area. The 10’ beam was also a selling point, every extra bit of space, I appreciate. I have been able to shower on board okay, but if there is a marina shower available, I usually choose that option. As far as trailering, not a big deal. The widest portion is 8’ off the ground and tapers down. The trailer tires run in the same track as the outside duals on the pickup. Doubt this helps as you are considering the older style, but I certainly appreciate the space on the newer style. Let’s face it, I am not built for most of the world!
