Gas can carrier

Modding this should be easy - have a shop plasma off the 5 bolt pattern mount, and weld a plate with a 6 lug pattern.

That looks like a good idea! You might be able to just re-drill the mounting plate for the 6-lug pattern, rather than pay for a shop to do the work.

A question, what about weight? Do you have your spare on there? With a spare (75#?) + highlift (40#?) + 10 gals of fuel (60#?) + toolkit (10#?), you are starting to put quite a bit of weight on the back. Especially if some is farther from the mounts - it will put more leverage on the mounting points that far back, when you do it you might want to check the mounting points regularly to make sure there isn't deformation of the sheetmetal on the door.

Harbor freight tools has this in there catalog.I couldnt find it online.
You would need a roofrack though.


I have a petro pump(harbor freight also) on my 5 gallon can,very handy and does not leak.
I use my work car for transporting gas or I just take it out of the 442 when needed.

Well, that's going to be the huge question.

A 20 Liter Jerrycan (I use NATO spec ones on all my trucks) are 33lbs full of liquid. A 60" Hi-Lift is 40lbs, and a Pioneer Toolkit is about 20.

So, if you did the loadout that I'm looking at (10gal fuel, Hi-Lift, and Pioneer), it's 126 lbs. The sad part is that I have absolutely no idea if the rack mount itself is rated for that level. I do know that the rack is adjustable to handle anywhere from an 8" to 13.5" tire width, so one could minimize the damaging leverage found in hanging something like that and place it close to the tire.

The other thought process is to modify one of those tire mounted bike carriers and hang stuff off of that.

Or - go the Thule roof rack mount method and get a known good capacity...which is roughly 80lbs per bar. I just hate having a roof rack - it screws with fuel mileage.

Maybe a question to ask - what is the largest wheel/tire size anyone has hanging on the back door and request an estimated weight. Deduct this from your wheel/tire weight and that would provide a safe weight that could be added.

Well, I just called Olympic. They claim the rack can handle 75lbs with the stock spare tire mounts (on a Jeep Wrangler back tailgate with the stock tire). The rack can handle up to 200lbs of stuff on it when you use a swing away tire carrier.

Now the next thing is to call Hummer customer service....see if they know something about the swing gate max weight (ha!)

One other thing. I'm 200# and can step on the tire carrier (no tire) with ZERO deflection of the rear gate. I use it as a step to get up on the roof rack. At the door, It's solid, but when I use my bike rack stepping down off the rack (the bike rack bolts to where the tire used to be), I feel deflection, but can't see it. Might just be my imagination.

That's where the leverage comes into play. Your bike rack is providing a minimal amount of leverage that could translate into flex of the mount.

I found the solution! It's not the one I prefer, but in absence of a proper swing away system, it's the best that I can find that doesn't screw with the mounting system AND it's within the weight range.

There's a bad thing - people who want it has to hop on getting this stuff NOW.

Here's the details:

ConFerr (who is now out of business) makes a fuel can carrier and spare tire adapter.

The spare tire adapter can be had with a 6x5.5 bolt pattern (which is what our H3's use). A picture from a supplier (who still has stock supposedly) is here:
http://offroadrecovery.zoovy.com/c=V...wV/product/G81

You then mate it with a ConFerr fuel can carrier. The fuel can carrier uses Blitz cans (not my favorite brand of fuel cans, but it's usable until I can figure a way to adapt a normal bucket type carrier to the adapter).
http://offroadrecovery.zoovy.com/c=V.../product/G8007

Total cost - about $120 after shipping.

If you want to even attempt sourcing this out yourself and not get it from OffRoadRecovery.com in Colorado, here's the part numbers you'll need:

G8149 - 6 Lug 6x5.5 ConFerr Blitz Spare Tire Can Carrier Mount
G8007 - ConFerr Blitz Can Carrier
And of course - a Blitz branded fuel can. Be aware that the NATO 20L clamshell welded tanks (the ones I tend to personally use) are NOT compatible with this setup.

As soon as my stuff arrives, I'll take pics of the mounting and post it.

Well, that was a fast reply - not from Hummer corporate, but from the regional Hummer Product Manager. Figures that corporate is slow...I'll probably get my answer from corporate customer service in 2 months.

The regional product manager says that 33's nearly maxes out the mount on the back door....combine that with other stuff, and you're looking at a max of about 75 lbs hanging off the back of the mount at most.

Sucks, huh? Now I need to find someone that makes a NORMAL swing away carrier for my wife's truck.

Biggest tire they've tried and tested is in trials is a 35" tire with a 20" wheel...specfically a BFG AT TA/KO in 325/60R20. Just the difference in wheel weight plus tire weight is easily 50-60lbs.

Something like this would be cool.

Or...the standard cans are 6.5-7" deep. The rear tire mounts (sans tire) stick out 8-1/4" from the rear gate. You could fab up up a mount (aluminum would be best) that mounts where the tire goes, and the cans go INSIDE that up against the door. Would reduce leverage, and would also protect somewhat the cans.

oooo, then you could also mount a small rack on top of that, to put small stuff (like tie straps, etc) above the tire mount. Have the floor be expanded metal so you could put wet things, etc. Or make a lockable box there for your recovery equipment. As long as the weight is up against the door, I think leverage would be minimized and you could put 100# on there.

hmmmm, looks like I have a weekend project!

Something like this I hacked together in visio

If you use the tire mount carrier, you will still see some 'leverage' on the door, that might be an issue.

As for the roof rack, I see ~1-2 mpg difference across the board for mileage w/my rack (with spare). I imagine that will go down when I get around to putting a fairing on it, we'll see. Good luck!
