DVaughan,
I have a 2500 series 9. 5' slide in that I just bought. Did alot of checking and looking before I bought and although I didn't look at every brand available, the Bigfoot was the best built IMHO. A couple were close, but none were better and most weren't in the same league at all. The literature on the trailers seem to indicate that they use the same construction methods, so I am sure you will be happy.
By the way, I have friends that have a 2500 series 10. 5' and a 3000 series 10. 11 as well. Zero problems with the units themselves (the usual dometic circuit board issues and innovative battery solutions), no leaks, no cracks, etc. We all ride and race offroad motorcycles and use the units often. Roads always are gravel in various levels of repair. Using 4x4 is common.
I am sure you will be happy. Enjoy
Dave
