"Anyone know anything about Lance trailers"
We have a Lance 1685 (smaller than what you wanted but perfect for us). We've taken it alot of places where there are no other RV's - Chaco Canyon comes to mind. But not really "off-roading".
It's a well make trailer, just remember that any trailer being hauled down the road is subjected to 4.5 on the richter scale for hours at a time. But our Lance does well.
For more on the reasons we like it, I wrote a blog post
Why We Love Our Lance 1685 Travel TrailerThat being said, our friends that owned the big sister to our Lance (the 1885) and then moved to Whitefish, MT, sold their Lance and got a Nash which they like even better. They do alot of seriously off the beaten path hunting and like the higher clearance and sturdier construction of the Nash (manufactured by the same folks that make Artic Fox).
If you decide on a Lance, you may want to investigate adding a lift kit since the Lance sits lower to the ground than Artic Fox or Nash.
