Adding on to M1079 Box

[AlienFood]

Howdy

New here...but have been looking through the posts and all the wealth of experience/knowledge available from you all.

Seeking some advice on how to add an extra 5 feet to the back of an M1079 box. Examples being TravelTheGlobe's first LMTV on youtube of course, and The Overlander Project's Blue "Stewie".

How would one make the addition to the box structurally sound? Would it involve welding to aluminum?
Best way to go about insulating after?

Thanks for readin'

Theres not a lot to weld to on those boxes ! Maybe 2 ft on the front and 3 ft on the rear with a lot of fab work and drill and rivet to the front and rear box frame of the 79 box . Dove tail the rear 3 ft section back to the 79 box at the tail lights so as to not mess up your approach angles .

Heya!

Thanks for the heads up. From the few examples I see, "looks" like steel square tubing is bolted to the back of the box. And dove tail seems to be a law of LMTV box add-ons Lol.

But then best approach on sealing all the small gaps between surfaces/sheet steel, tbd.

Man is that your build in your photo? Looks heavy duty with the shipping container...and some crazy fab work to make the approach angle

SIKA 221 SIKAFLEX is hard to beat . There are a few windshield urethanes like 3M but they are expensive ! And yes thats mine you can look thru my build page and maybe get some ideas and improve upon ! That the beauty of this build forum is all the different builds and ideas in one place ! @Third From Texas is building a 1079 down in Corpus check his page out too !

Chucky I gotta ask...what kinda speeds and MPG are you getting with the 6x6?

A few M1079 builds have added an extension out thru the rear doors.

If I were extending the box, that would be how I'd do it.
At one point, I considered a slide-out doing just that (extending out a couple feet when retracted, then expended out several additional feet when deployed).

This is what I originally wanted to do:





Some random images (none mine):









This idea seems like a great support mechanism for a slide-out or rear porch. The M1079 could do it with the smaller/upper rail:

50 mph and 6 or 7 mpg and what part of the Lonestar are you in ?

I will come back to that SIKA 221 SIKAFLEX. Saved.

Pretty cool, @Third From Texas. Build I am looking to do would require the permanent space of a fixed rear add-on.
Trying to compromise between having small knife making "shop compartment/garage" and full living quarters including space for power/100+ gal water, kitchen, bathroom/shower, fixed bed.
