The rack I built my self. I had a design in my head over a period of a year and figured out just where I wanted everything. It' s still not complete as I want lights mounted under the front space for the backroad night travels and I have a few more things I want to add to it.
It definitly is a leather man of roof racks. It flips here, this bolts there, you can add this that and the other thing and it is very strong. I can carry 4X8 sheets of plywood and the front and back come off for a flat platform.
I had a friend of mine that does metaleragy work in CAD and solidworks programs, he told me to give him all my drawings with metal thicknesses I used.
He put it under load in various situations along with force of load under bouncing (kind of an off road situation simulation) and the thing will hold at it's weakest link a load of 1700 and some odd lbs. For a test, 6 of us at work stood on it and bounced, all of us average around 200lbs/person (me being 225 and another 185 etc.) it never flinched.
He thinks I would be able to drive a Quad up there and still have no problem, not that I ever would but I like things built over kill.
I'm hoping to get in a 3yr fabrication course apprenticeship this spring and start in doing things just like this. We'll see how the waiting list goes. Other wise I will go back and do a welding apprenticeship instead of the welding artisan general interest class, which I had taken.
I won't take up your thread and start a build thread of my own on my rig one day soon.
I would like to of had an older Ramcharger like a pre 1980 for the removeable top aspect but I'm a Dodge guy thur and thru and this one had low miles on her so I could not resist. I was waiting 4yrs to find the right Ramcharger rig. Other then the fact this one has a solid roof, but being a newer year with the MPFI magnum, makes up for not being able to pull the top off.
Cheers.
