We had a FR wolf pack 27 WP to haul our two full size Harley Trikes. We could easily get them in there end to end, but once they were in, you were not using the camper until they were unloaded. So we started looking for a 5er with at least a 14' garage, but did not find one we liked, as the living space just got smaller. We fell in love with the new Vengenance 39R12, and after some measuring, figured we could get the trikes in there, so we bought it on the spot. The TH is actually 41'-7" 13k empty, 18k gross. The first trike gets backed in on the right side (yes I have reverse) and the second one pulled straight in on the left. Both are 4 point strapped. Unless you have something that really needs the length, you might want to check out the 39R12. 60k price range, if you shop.
