By the way, the 416 403 and 406 have a near identical look, but the 403/406 has a wheel base that is actually shorter than a CJ-7, which means you can tip that sucker over in any dirrection really easily.
If you are going off road, I agree, go for a longer wheel base.
I am 6'5 and I fit, only just, into a 416 DOKA, but I did fit really nicely into a U1300L. You might keep your mind in the SBU trucks if you are as tall as I am. If you see a 404 just run away, there is just no room in them for a taller person, you will hate life driving that thing. (I have, and I enjoyed it, but no way I could drive one for more than ten or fifteen minutes, too tight.)
You have a lot of great advice on here. Keep reading, you can find lots of stuff out there. Also find some local moggers and see if they will take you for a ride in theirs. SPEND The TIME before you spend the cash! I have always wanted a mog, and I liked the 404 a lot, until I drove one. Now I know that if I get a mog I need to be in the 50K range for what I am looking for, which means I can stop looking until I can afford that kind of truck.
Best of Luck!
