I love mine.
Yes, it's strong. Stock it handles up to 35's. Imitations attach to the tailgate for strength. The Bestop attaches to the roll cage inside and to the lower body mount. No weight is put on the tailgate.
The thing I like about it is to open the tailgate you just open it like it was stock - pull open the stock tailgate latch and open it. The Bestop swings out with the tailgate. . No fumbling, no pins, no clamps - just open it.
If you want to go to a heavier bigger tire it's easy to strengthen them too.
