1) My axle was indeed bent during the first year and covered under warranty.
2) I love my trailer. Every TT has their positives and negatives.
But I believe you will have that with any TT.
3) The bed may be an issue for you. I'm 6'2 and its tight. I was lucky enough to get the comfort package ( water filter, central vac, upgraded pillow tip) which is a much better mattress. Most stock TT mattress' are horrible.
4)The gray and black tanks are ( in my opinion) smaller and fill quicker on this TT. The gray more than the black. When there isn't full hookups it can be an issue depending on how long you stay. 90 percent of our stays have full water and sewer so its never a issue for us. Remember the BULLET PREMIER is much lighter than others because and I'm sure they had to make sacrifices to keep it under 6400 lbs or whatever the dry figure is.
This is my first TT, so I would say it is good. I had initial towing weight issues but the models I compared it against, this was built better. I would look at KZ Spree. A little heavier but well respected as a legit competitor.
The outside kitchen is plain awesome. Storage isn't great. That's it for now.
Good luck and take your time. RV Shows are your best way to compare build quality.
