    Default HMMWV 4-man Soft Top Slant Back

    I've begun making a soft top for the bed of my HMMWV, in a slant back design. I know that covers exist which extend the roofline back to the tailgate, but I wanted a sloping appearance more like the fiberglass slant backs.
    I'm not aware of anyone making or selling these, at least not in a price point I can afford.

    Construction is from standard contractor grade 1/2" EMT steel conduit. I'm using standard couplings and a couple of 1/2" iron pipe elbows to serve as the major unions. I've cut apart some screw couplings to serve to join inside portions. I don't know yet how well this will work, but it will be interesting finding out. I'll cover all piping with standard foam pipe insulation to cushion the canvas and give me something wider to wrap velcro straps around. I plan to use the same type of velcro approach as used in the standard soft top, but I don't plan any padding.

    My prime reason for making this, besides looking nice, is to keep a majority of rain, debris and snow out of the bed. Given that the M998 HMMWV is a pretty "airy" design, I'm trying to get less water intrusion into the passenger compartment and not have to worry about being parked nose uphill when there is a threat of rain. I now some folks have made bed walls, and that's something else I might could do.


    If this works, I may make some to sell, if there is interest. If not, there will be enough pictures at least for someone interested to bash out his own. The sewing will be the hard part, obviously.

    Here are two pictures showing how far I got last evening. All the corners that are taped will be welded this weekend, except the back corners which I am thinking of bolting to the union. I'm trying to make this easy to assemble, with an eye towards possible future sales and being able to ship it rolled up, or just being easy to make for a DIY-er. Some of the necessary unions don't exist in the average Home Depot aisle, so that's where I'm welding. I'm not a stellar welder, so this will be good practice for me. I'm getting better, and the repetition will do me good.

    The large cavity in the center will be for a marine vinyl window. I will remove the rear curtain when using the slant back, and plan to get one of the suction cup rear view mirrors from the marine market that some on the site have used with good results. It will be nice to have a rear view mirror to add to visibility in the side mirrors.

    Good idea. Surprised nobody has done that before.

    Default Making progress

    Finished the mock up and got most of the tack welds done yesterday afternoon.

    Had to stop welding due to loss of light. Woke up this morning and hit it again finished off all the welds. Then tidied up the back corners. Then put the padding on.

    Pictures of all the padding mounted. After some errands and chores I will see about starting pattern making for the canvas top.

    I don't see any hatch support structure.
    Have you though about making the whole assembly hinge-able like hatchbacks?
    Grocery shopping would be much more enjoyable if you could pivot the whole assembly up.

    I would attach lots of velcro strips under the cover (like the softtop) or that will flap up and down like a SOB.

    Mario, yes I have given a hatchback some thought but haven't quite wrapped my head around the moving parts necessary. I decided to stop hemming and hawing and get to cutting steel and stitching canvas. Mark 2 will be hatchback.

    Action, yes, exactly, I have some heavy velcro to use just like in the soft top.

    I'd be interested in the purchase of a slant back made of canvas. I agree I think its a great idea and can't believe no one else has created this yet that I have seen. Good luck looks great so far. I also think the hinge idea would be genius to make the back more accessible.
