It's a nice looking trailer. A 416 just went around here for $675 - painted and all but when you got up to it you could see lots of dings in the tub. They do command a price. And a decent 101 without the racks, bows or tarp and non-OD paint job will be well north of that.
I'm wondering about the type and gauge of steel in this unit considering today's market. How does it compare to the original? The quality of the material throughout could be a big tipping point in price if it's not of the same stuff you see in the utility trailers at Lowes and Tractor Supply.
While I can certainly see this crowd or the likes on the 4x4 sites putting something together for themselves from surplus, I can see a segment of the market willing to pay rather than fix, build or paint. I'm thinking in particular of the person around here who has a Jeep set up for off road to the teeth but that has never seen mud outside of the potholes in the dirt parking lot at the county park.
Seems those people have lots of money to spend, the desire to look like they're ready for the hinterlands, but would prefer to do so bringing big stuff home from the big box store or going to KOA.
Best of luck in the endeavor.
