At GovPlanet you can get the truck for $6-8k and the trailer for under $2k so let's say $10k for the combo. That leaves $30k to build out the box and paint the truck and still break even selling it. Personally I think it's a tad overpriced for something that can only do 58 mph on flat ground (it's governed at that speed) and barely do 45 mph on a slight grade (pulling the trailer will drop both of those speeds). Having owned a LMTV and multiple other military vehicles I know they're great fun to play with as long as you don't have to drive any distance with one.Which is why the $40k price tag is alarming. From the listing it seems like the trailer is included too! If it's legit then someone's going to get a great deal.
