Rear Door Accessory Mount for non ladder owners

[GPFACTOR]

In case you dont see this in our Vendor thread, I tried to post this in the appropriate location on the forum as well. Cheers!

We are proud to introduce another awesome accessory for your Ineos Grenadier, our Rear Door Accessory Mount! This mount required no modification to your rig, and mounts in the same spot as the factory ladder. This is a great add-on to your Grenadier if you do not have the rear ladder, and are looking for a great place to mount a variety of accessories. We designed the mount to be as low profile as possible so accessories like Rotopax and Propane tanks do not stick out past the spare tire. The mount is constructed of .125 Stainless Steel, with a durable Textured black powder finish. The Mount comes with a standard Rotopax Mounting pattern that can accept just about any Rotopax accessory, or other mounts (like our propane mount) that have that same pattern. The kit comes with spacers, specifically sized for each mounting hole. The spacers allow the mounting bracket to sit on the spacers , and not crush the rear door plastic panels or body on the bottom of the door. Included with the spacers for the mounting holes is a series of rubber O-rings to insure a proper fit to the factory mounting locations.
*ROTOPAX MOUNT NOT INCLUDED*
SPECS:
Material - .125 Stainless Steel / ASA UV Rated Polymer for the spacers
Finish – Textured Black Powder Coat
Hardware – Stainless M8 BH Screws, SS washers, Oil-Resistant Buna-N O-Ring

Any plans to broaden the idea of this to mount jerry cans or such? I'd love something like this that direct mounts rather than needing a ladder.

I have the GP rear door mount and am playing with mounting NATO 20L Jerry Cans on it. I’ll let you know if it works or if I have to use Rotopax.

Any update on this? Have you tried a jerry can on this mount?

20l/5gallons seems a bit heavy. The LeTec ladder that also hods a full jerry uses all six mount points for the OEM ladder. I think they said 30-35 lbs when I asked for an estimate. 5 gallons would be just shy of 42 lbs. plus the can. I'm considering a 3 gallon Rotopax or the largest Overland Fuel can that will fit.

I did it with 4 gallons. All good

I received the GP mount and a NATO can but waiting on the NATO mount. I’m going to start with one can and then order a mount for two cans. I don’t see a worry about weight. That ladder is designed to hold a full size man. The fuel will weigh 60 pounds and add another 30 pounds for tanks and mounts. 90 pounds doesn’t seem all the much for mounting points for a ladder.

They might suggest that because you still have to add in the load of a person on the ladder.

Static load is different than than dynamic. Heck, you can climb all over the ladder with only the ladder door shut and the spare door open - but not while moving. Additionally the ladder is made from tubing and is very stiff but there's no gusseting on the GP mount. It is slightly flexible and the mounting bolts are small. The spacers are not integral to the bracket (though tightly drilled) introducing a second fastener failure point. I'm not saying the mount is made poorly or sub-standard. Not at all!. I think it's great. I would just be leery of mounting heavy items to it and then running thousands of miles of rough roads. If you never suffer any issues then fantastic! I'm happy to find out I'm just overly cautious.

Another ladder mounted jerry can holder in this thread...

Thread 'Design-Build-Go install and review of DVA Mechanics accessory ladder mount.'

Nov 24, 2024

Today at the Design-Build-Go shop we are trying out the www.DVAMechanics.com accessory rack for the Grenadier. This rack has numerous holes so the type of accessory is about endless. The center to center bolt distance is 6.5" so what ever you want to attach, you can set it for that or even adjust to smaller distances. If you need a large distance than 6.5" you could easily make a plate adapter. For this video we added the Jerry can holder that is available from DVA Mechanics as well. I found this installation easy and enjoyable. The adjustability it has is really cool and the ladder...

Static and dynamic are very different but 90 pounds vs 330 is also very different. I’ll give it a try. Absolute worst case is that I need a new rear door at some point.

I thought they originally bragged that the ladder could be used with just the 30 door closed. Either I imagined it or Ineos changed their mind.

 

[Theoretician]

The best tires can generally achieve about 1.5g in lateral acceleration, which represents a 0-60mph time of two seconds. From that and my experience in engineering, I'd be comfortable with reducing the 150kg static load rating on the ladder to 100kg in any non-impact scenarios. Take another third off of that to reflect using four mounts instead of the full six and you're at 67kg dynamic, or 147lb, capacity for the mount and attachments. You could cut that down to 50kg for some additional conservatism if you want, reflecting a dynamic amplification factor of 2 instead of 1.5.

That C4 dual jerry mount has 21lb of steel involved, and two full jerry cans weigh 80lb, plus 10lb for a strap and hardware and such, for a sum of 110lb - right at the conservative DAF of 2. I don't see an issue with the weight.

I have some ideas floating around about an aluminum pseudo-ladder. Tie in to all six mounting locations, have a dual jerry mount at the bottom, then options for mounting a shovel or high-lift vertically on the outside runner and a propane tank or small shovel on the inside runner above the jerrys. You'd probably have 50-100lb of payload after the jerry cans - plenty for a 30lb high lift and a propane can.

I got back from Utah and finally had some time to put the NATO Jerry on the door. Easy install with only 4 holes to drill. I have a second NATO can and am looking at what mounts would work the best.

Hope you're right. It'd be great if we can mount that much weight to the door long term. I've actually been inside the rear door and poked around a bit. I will wait for you to cross Australia a few times. Let me know how that goes.

My use of the GP mount is for carrying extra fluids/lubricants, shovels, and possibly traction aids - stuff you don't really want inside the vehicle long term. For heavier loads a tie-in to the rear bumper would alleviate some vertical shock load concerns and stress to the hinges and latch mechanism.

It is the GP Factor rear door accessory mount. That comes pre-drilled for Rotopax. I'm not a fan of plastic fuel cans and prefer the real NATO Jerry cans (not the Chinese junk you see everywhere). The Jerry can mount came from Wavian https://wavianusa.com/gas-can-holder-front-loading-20-liter.html?cgid=wavian-holders

It would be great if @GPFACTOR pre-drilled the door mount to accept the Wavian Jerry mount. It took some measuring and screwing around to make sure the can was high enough not to hit the bumper with the door open and low enough to easily get to the door handle. In fact, I screwed up the first time and had to re-drill holes up a 1/2" and to the right 1" inch.
