You are going to get far more positive responses on the Big Horn than the Bay Hill due to the fact that the Bay Hill has only been out for three years and there are literally thousands of Big Horns on the road. We looked at and researched both and decided on the Bay Hill 340RK due to the floorplan. Both are quality units and both have pros and cons from our perspective. Not sure why no molded rear cap is a concern, but you have to decide. The key is to be happy with your decision and I don't think you will go wrong with the BH. Good luck and safe travels.
