How about "Liberty Ship" as it gives you the freedom to go off road?

Did you model the tires, or were they available from a manufacturer's web site.

that sounds pretty good, I got the tires off of a CAD site that anyone could download them from.

Free 2D & 3D CAD files, models and drawings of mechanical, electrical & mechatronics part catalogs.

Thanks for the link!

I am starting the frame and am wondering if 1/8 wall 2x2 square tubing is thick enough or even to thick. What are your thoughts on that.

Did you run Inventor's stress analysis routines? I'm not skilled enough with the software to know how to work that part of the program yet.

Gut feeling is that 1/8" thick is the bare minimum, and 3/16" the maximum. Though I think 3/16" would be overkill. Mind you that's a guess.

The area around the articulation joint and those parts I would do out of 3/16" wall . There is going to be a tremendous amount of force from different angles that the structure needs to deal with.

The rest of the structure I would use 1/8" and double up in areas of higher stress.

Yes I have played around with the stress analysis but not that confident with it.

I planned on making the joint area heavier than the rest. Your right that it will need to be strong. If that fails I'm screwed. It defiantly the most important part of the machine.

who makes the vehicle in the pictures?

I haven't read through 13+ pages but the solution has undoubtedly been mentioned. Just bolt on four wheel motors from a zero turn mower onto an old 2WD ATV. Tuff Torq lists the specs on their web site.
