    Here's the 1/4" Aluminum Plate, powder coated black that replaces the passenger seat. (6) 5MM 1 1/2" screws needed to accommodate new thickness.
    I designed the plate to follow the contour of the rider seat...and leave the 'rear' attachment point for the passenger seat for future possible use. Note that the other (6) tie down slots on the passenger base remain available for continued use.

    I wanted 4 Gallons of extra capacity so I got (2) 2 Gallon RotoPax, along with the required Extension, "L" mounting bracket and the LOCKING version of the handle.

    When mounted...there's still a need for some additional support at the front of the second mounted 'pax' so I designed a 'support bar' to provide such support.
    This picture shows the "L" bracket mounted toward the rear of the bike...wouldn't want to have the 'pax' the first thing that's encountered should someone/somebody inadvertently decide to introduce themselves to my bike in an abrupt manner. Read as 'rear end me'.

    Also mounted a thin rubber gasket between the 8 gauge STEEL "L" bracket and the 1/4" ALUMINUM plate to prevent any 'metallic interaction' otherwise known as corrosion.
    Found the 6" x 6" x 1/16" gasket material at Lowe's. It's in the plumbing aisle. Called PACKING SHEETS. Cost: 98 cents.

    And, finally completed project.
    Please note that 'fillers' on pax are on the OPPOSITE side from the muffler...minimizing ignition possibility.
    Also...have called Jason at RotoPax and swapped Pax with VENTS at the BOTTOM for VENTLESS paxs.
    Be sure to get the VENTLESS versions if you plan on mounting the pax HORIZONTALLY.
    I was concerned that the VENT'ed versions might leak...being on the bottom...that might be a problem.

    Another beauty shot of completed project:

    The mounted pax still leave 8 1/2" between pax and rider seat...room enough for a big NORTHFACE duffel which arrives tomorrow.

    The AOL links don't work - they ask you to be logged in.... can I have your user ID and Password? :D Just kidding - please don't post them!

    Perhaps I'll get to see this in person this summer when I do my 2nd attempt at Prudhoe.

    EDIT: The changes you did work great now!

    Photobucket is free. Once you've got the images there, they give a set of address to them - copy the one that says "direct link", then here in the reply to thread window find the little yellow icon with the mts in it, then paste in that direct link address.

    If you are tooooo popular, you'll exceed the free bandwidth - but its worth a try, and I haven't posted anything that's pushed the limits yet.

    Get'er done! I wanna see these pics since I want to do something similar!

    Picture 'stuff' all 'sorted'...as they say in Australia.

    Thanks for your help with getting them from my computer to AdvRider!!!:clap

    That's a nice set up. I plan on going that route as well.

    The setup looks nice, but my concern would be 20kg of weight that is now sitting quite high up on the bike.

    Would you not be better off putting the can on your panniers to put the weight down lower?

    That was my thought...keep the weight low and in the middle:deal

    I thought long and hard about where to place these. Have seen others place them LOW (back/side of panniers) to keep the CG down. My concern about LOW is contact from others (cars, trucks) from back or the side. Not to mention contact with terra firma due to unknown and unlimited number of possibilities. Total filled weight is about 34 lbs.

    My solution is HIGHER but is still on the centerline and the "L" bracket that's provided is 8 gauge and is ROCK SOLID. And, with a roll duffel immediately in front of (good backrest, as well)...I'm not too concerned about the wind resistance either.

    Practically speaking...LOWer and Centerline are good observations...but there's no perfect solution.

    Thanks for your comments.

    Update: March 10, 2010
    The Northface Duffel and the VENTLESS versions of the pax arrived today. And, based on other rider's comments above, I've decided to store the EMPTY PAX in my duffel until such time as I will need them (probably for the Fairbanks to Prudhoe Bay segment). They lay flat and the duffel accommodates both of them just fine. I'll post pictures tomorrow of the 1 PAX in use...1 PAX stored tomorrow.

    In case I can't remember WHERE I'm going...just look BEHIND you!!!

    And...here's the 2nd RotoPax stored empty within the Northface 15 x 15 x 28 duffel. Will only attached to "L" bracket and FILL when I'm in Fairbanks headed north to PHBay. 5.3 + 4.0 = 9.3 * 50 MPG = 465 mile range...well enough for the 421 miles from Fairbanks to PHBay.

    Good looking solution, LPOL! :D

    Could the vents on the Rotopax be used as fuel line attachments?
    That would mean that you keep them fixed in place and a valve+fuel line arrangement feeds the fuel to the main tank so you don't have to take them off to transfer the fuel?

    I commute daily with the OEM top-box bolted in place for secure storage reasons. The solution you found makes me think of using two brackets to mount a Rotopax fore-and-aft on either side of the top-box...?

    You should talk to Jason at RotoPax about using the bottom oriented VENT ... in the original pictures I posted...as a feed line. I chose to go with the VENTLESS versions (sorry...the VENTLESS versions don't show up in these photos).

    I'd just be careful about exposing a 'pax' on the back of your top case. Rear end collision might ruin your day. I have the sleeping bag, tent and STEEL "L" bracket BEFORE the pax.

    Thanks for your thoughts!

    Did my 13.4k mile 'long way round' trip Michigan to Prudhoe Bay and back carrying 1.25 gal. spare gas on my 12GS (not Adv). Needed it once.... in desert of Nevada. If I'd been paying attention, I could have avoided that necessity. Carried the spare gas bungied to front of my duffel, used it as a back rest. I'll carry it again on next trip to AK.

    And...in case you want ANOTHER CONFIGURATION for installing (2) 2 Gallon RotoPax???...how about INSIDE a 35 L Caribou Case.
    Even LOWER center of gravity and another level of protection inside of a durable vented Caribou Case!

    just a thought on those 6 M5 bolts holding the OP rack. they are only threaded into a small clip that is held in place by plastic. doesn't take much to ruin those.

    Nice work! Better than I could ever hope to do.

    Just a thought: instead of having the fuel up there, wouldn't an Adventure tank have been a better solution? Probably way more expensive, but still...

    After looking at everyone's setups and thinking about things - and packing to ride two-up with full camp gear - I decided to go for a front mount.

    I went with the basic RotoPax mount and a backing plate, and filled the gap with a disc of HDPE plastic grooved to fit over the crashbar intersection:

    After completing our 3 week/4000 mile trip, I can tell you this worked well. Putting this weight on the front end helped with load balance notably. On our way home we didn't need the extra water, so I let them run dry. Noted the handling wasn't as good - so I filled them back up! We also had a Polar Bear soft cooler on top of the left side case with another gallon of water cold for getting thru AZ and UT where we were also using evap cooling vests.

    With packs mounted:

    Your setup looks pretty dangerous. What if you dropped the bike? You and your riding partner will be covered in fuel.

    I have a 2010 GSA with > 9 gallons fuel tank and I placed a pair of Best Products Peg Packers 2 gallons each on the passenger pegs. Low center of gravity with 2 gallons on each foot peg. I will only ride Solo after being hit by a Drunk Driver 3 Years Ago, so I don't need passenger pegs. I can carry either water or fuel. With 13 gallons of usable fuel and > 40 mpg I can get over 500 miles between fuel stops. Works for me. I got stuck in Oregon a while back with little or no gas available after dark. Worked Great!

    1) Those are for water - no problem. With a GSA tank and 8.5 gallons of gas I don't really need extra fuel.

    2) I did drop it once - a parking issue. The crash bar took the hit mostly, but with a little scratch on one corner. Rotapax are pretty tough, too.
