I'm a little biased towards the Premier 31BHPR ;) It's been an excellent trailer with no problems to date. It's very well built compared to many others we looked at. I did have to move the fridge in the outdoor kitchen over a few inches to allow the door to open fully and I plan on moving the kitchen door struts up so I can stand under it without ducking (I'm 6'2"). Both minor mods.
Since the floor plans are all similar and quality of TTs seems to be a******shoot, I would go for the one I could get the best deal on and/or from the dealer I had the most confidence in to rectify any warranty work.
Almost forgot, our delivered weight with all options was 6400lbs.
