There is a reason Andersen re designed the aluminum Ultimate.
Personally I feel Anderson makes a quality US Made product. BUT, IMHO their ratings are way too high. For one they can and will deform the bed since the base is just using the bed to keep it stable. Hard braking or accelerating with a heavy RV will cause this problem. The old B&W Companion did the same thing (i know from personal experience) until they re designed it so the base placed its pressure points to the low part of the bed corrugation and to the bed cross rails.
I would consider an Andersen for the 250/2500 market but none higher. Oh, BTW the "crush test" video is a bit of a joke. How about a real world fore aft test???????
