Has anyone on here bought and installed one on an original M100 (or MBT) chassis? Just wondering how much fitting is involved and how close it is to original (design). There is one for sale (fairly) locally, still in the crate, bought from Bensinger in 2016. The guy is asking $100 less than new price (plus I would have to go pick it up ~ 550 miles away). Thought if I could get it for $700, I could slap it on my M100 chassis and be done with that trailer.

OK, so I called the guy and asked for his lowest price. He said $650 - I told him I would be there Monday morning! I got there, checked it out, exchanged $$$, talked a little Army (he is a retired Bradley gunner - I was a gunner, but didn't retire), now with the VA, and headed home.



I uncrated it and was pleasantly surprised! It looked to be fairly well built and accurate. I found a few things that weren't right, like the stitch welded seams on the floor (instead of roll welding - I won't be floating it anyway, so waterprrof doesn't really matter to me), end panels that didn't fit tight and a place on the top rail that was flattened a little.





The fender mounting tab holes even lined up!




Overall, I am very pleased with it.

Here is a link to my blog post with plenty of pics of the uncrating and inspection: https://wp.me/P8ig4E-zC

Yessir - I wasn't able to find much information on the MD Juan tubs online, so I thought I would share my own findings/info. I will update the blog page (and add some info/pics here as the project progresses.

Since I'm pretty much done with the USMC M38a1 and the rally is in the rearview mirror, I figured I would take a little break from the Jeep and do something different.

I decided to work on the MD Juan M100 today. I pulled the chassis over to the shop with the side by side and removed the springs/axle and front frame/casting/lunette so that I could work with it by myself.

The measurements for the trailer were spot on, but the problem came in with the center brace and the width of the floor pan. I had to trim the center brace so the frame wouldn't hit it.



Then, the width at the bottom of the lip wasn't wide enough at the rear end, so the frame wouldn't go all the way down like the front. I had about 2 1/4" reveal at the front (lip to the bottom of the frame) and 2 3/4" at the rear. I ended up having to raise the front up 1/4" so that it would be closer, but still not perfect. I tacked the front corners, then moved to the back and tacked them. Then I came back and welded all of the points down the side. For the crossmember welds, only the rear touched the floor all the way across. The middle crossmembers were about 3/16" low. I used a floor jack with a 4x4 to push the floor as close as possible to be able to weld them up.

Once I got everything welded, I scuffed her down and sprayed all of the pitted metal with Rustoleum Rust Converter before spraying 3 heavy coats of OD 24052. Hopefully that will be enough to keep the rust at bay for a while to come!


While I was prefitting, I threw a fender on it. The mounting tabs on the frame are about 1/2" too low. I'll cut these off and re weld them once I get it back together.
