Having seen the earlier truck bad-assery here, I decided to wander around the innert00bz and see what else I could dig up.

Immediately, I thought of Boyce Equipment in Ogden, Utah.  They have been buying, restoring and modding these ex-military beasties for over 40 years. 
Looking for military spec full size in good shape?

They got ’em.  And if heavy duty Chevy’s aren’t your style, they also have M715’s.
Need something bigger to haul around all your guns and survival gear?  How about a deuce and a half?

There is literally nothing these guys can’t do if you can dream it up.  One of my personal favorites is this bobbed M35.

In addition to selling turn-key trucks to start your own army, they also sell all the parts needed to build your own monster.
Elsewhere around the webz, I found this beastie on Engineerd’s Facebook page and nearly excreted a block of ceramic masonry material.

This M813 has been completely gone through and has been outfitted with $7200 worth of brand new bone-crushing Michellin XZL Tires.  My initial thought was to strip down a fifth wheel, mount it cab-over style, paint it to match and call it home.  Find it on craigslist for $13000.
Lastly, we have this lil’ guy:

The only thing missing is the hedge trimmer that goes in the mount above the cab.  Find this one on eBay with bidding currently around $13k and no reserve.
