Used the standard pax mount and some T-nuts/bolts

The single one works great and they're easier installing on the roof rack but if you run a larger jerry can like the 4 gallon pax, the RX-UP universal mount worked better, it's just a little harder to install on the roof rack but not that bad.

I also used the off brand RX-LOX just to experiment and they work ok but the rotopax brand T handle may not fit the off brand mounts. The quality isn't as good but not too much drop off and on my several trips they've held up.

Next time I get another mount, I will stick to the rotopax brand.

This is the long rotopax mount

This is the off brand RX-LOX lock and mount thats worked for me as noted above

 
Pro tip for anyone mounting their Pax containers horizontal as shown in this thread. Carry a strap wrench for tightening and loosening. I've carried mine this way about 8 years and the strap wrench really helps with preventing leaks.

This was exactly the thread I was looking for. Thanks!

Thanks for the tip. The last thing i want is fuel dripping on the roof.
 
Thanks for your pictures b407, they help me see. The sides of the OEM roof rack are near useless in terms of strength and readily usable mounting points (and I also find the rubber tool holders only last for a trip or maybe a season before stretching and getting too loose, hope I don't regret switching to a Gerber folding military style shovel!). I am also disappointed that the extreme front- and back-ends are plastic air foils and therefore not really usable to mount or support anything.

I am also looking to supplement my 25 LC LE fuel supply as well as get the traction pads and some not so frequently used camping/recovery gear out of the interior. I wanted to ask you about how rough the treatment the rotopax containers gets on your rack- it appears the "cans" only get supported by the center area lockdown mechanism. I was worried that a plate such as the one mentioned by OverlandMethod or this related plate might be needed to support the rotopax containers on more rugged trails and heavily washboarded roads. It would seem that the situation might get worse if the rotopax containers are double stacked. Your thoughts?

Sorry just now seeing your question.

I haven't yet mounted four 2-gal Rotapax (stacked) on the LC, but I did so routinely on my 5th Gen, using Rotopax's double mount plate, which I regretted buying. Idiot CAD designer at Rotopax spec'd the main mount holes for the standard 5/16" (if I remember correctly) hardware too small; i.e. they drilled a 5/16" hole for a 5/16" bolt... which obviously does not work. Argued with customer support on that one for a while, and they basically said: "Tough shit, drill it out and use some Rustoleum where the powder coat was violated." They refused to admit their design error, even though it was blatantly obvious to anyone who tried to use the stock (provided, standard) hardware on a manufacturer-designed and produced mount plate.

I feel like the (smaller!) mounts on the LC are more secure than on the 4Runner, and indeed it could be because of the extra stacked containers that I have not yet mounted. That said, I will not hesitate to mount all four Rotopax when needed in the future, and certainly would occasionally check if still secure after running significant washboard roads, etc. They would slowly vibrate loose on the 4Runner for some reason I cannot fathom, considering how tightly they were secured (by hand).

Even the 1st Gen Rotopax are pretty robust, and I used my first set for years before they ballooned and Rotopax replaced them under warranty (kudos to them for that). Will not worry about my current 'small' mount surface, and have never had a 1st Gen container leak at the threads.
 
I definitely didn't take the economic approach but it should be extremely robust. I used a modified Backwoods Adventure Small Panel and a RotopaX Deluxe Mount to create this-

The holes were drilled intending to provide maximum mounting flexibility on the FE/OEM roof rack - the plate can be repositioned across the entire rack...almost. Spacing shown and use of two plates won't allow installation of a 4-gallon RotopaX can. It appears that adding 1 more hole or offsetting the entire rack mounting hole pattern by ~ 1/8" could allow the added flexibility while still maintaining support for 2 stacked cans by adding the extender. The entire RotopaX can is supported in this approach.

(BTW I have been less than awed by RotopaX hardware and mounting surface details- it does seem like some product design improvements could be made easily and improve the usability)
 
I was able to use the regular Rotopax mounts on the FE rack, holds them very securely, but I've only carried 4 gallons (i.e. 2x 2-gal, not yet carried 8).

Shovel mount on side not optimal for my current shovel, but bought an adapter that pushes the mount out a bit so it will not contact. Sides are a PITA to mount to. Somebody should make a replacement (stout) aluminum side panel, with more standard mounting hole placement.

Rear mount plate used for a Pelican box.

I like that set up. Did you notice any wind noise with the box?
