My Richards chassis is structurally fine but has some worksmanship issues. For one, the doors never aligned with the relativee precision of the factory frame. I suspect this has to do with the bulkhead mounts. Another big issue is the front bumper. There are two tubes on each side where the bumper bolts pass through the frame. On one side, one of the tubes is not straight, causing the holes on the factory captive plate to be about 1/8" off on one side, enough to make it completely non-functional. To fit my bumper, I had to manufacture my own captive plate with a wider hole spacing.
Now that I'm doing my own welding, I appreciate just how difficult it is to get perfectly square alignment on everything but these guys should be pros and I expected better. The doors issue is particularly annoying because my truck leaks like a sieve and no amount of door/bulkhead/tub maneuvering, hinge replacement, door seal replacement, etc., etc. will fix it. I've literally spent whole weekends trying to get the doors to seal and shut correctly.
If I ever do this again, I will look for a Marsland chassis.
