Just pulled the trigger on a 2011 80GS.

Those dimensions sound about right - I can't find my notes on the project right now but my Amazon history shows I purchased a Barker model #11917 - which has the dimensions you listed.
The toughest part of the project involved rerouting the water lines to accommodate the new tank location. I didn't have a lot of experience with the plastic pipes and connectors. Once I figured it out it was just a matter of fitting the pieces together in a way that everything fit - that tank fits the space but there's not a lot of wiggle room.

Thanks for the info Bob. Question. Did you use the 22" x 14.75" x 20" Barker tank? I was thinking of making a shelf over the black water tank and relocating the battery there. I would then put a narrow tall tank all the way across the back of the compartment where the current tank resides.

Hi Mike008!
I have the 80GS as well and found the water capacity to be a problem (esp. if you want to use the shower!). I was able to replace the original tank with a Barker 26 gallon tank. The new tank fits (very) snug on the left (drivers) side of the compartment. After I removed the original tank from the right (passenger) side of the compartment I moved the battery (I have an AGM battery that doesn't require venting) from the left to the right side; moved the inverter to the right; and repositioned the 7-pin connector. That gave me just enough room to install the new tank on the left side of the compartment. Its a very tight squeeze but it works. The extra water capacity really makes a difference and I am very pleased with how well it worked out. I used to have to refill the original tank on long weekend outings using a 5-gallong plastic Jerry can if we didn't have water hookups; that was a pain in the a$$.
On a similar note - we found the black and gray water tank capacity to be a bit limited as well (again, esp. if you want to use the shower). Easily solved with a Barker 10-gallon tote. If we fill a holding tank up I can dump it to the tote at our campsite and then just wheel that to an outhouse or bathroom to dump - just like a cassette toilet system. I found the 10-gallon size to be the most manageable (given 1 gal = approx 8 lbs).
Otherwise the 80GS is a great little camper! I like that fact that we can access it without having to put the slide out - makes it handy to load up and for stopping for lunch or 'stealth' camping.

Great looking setup. Any chance you could take a lot of pics for us when you do your jack conversion? Better yet a video?

On the water tank issue, if 10 gallons turns out to be not enough, after doing some measuring I see I can fit a 20 gallon tank with a little shuffling of components. We'll see.

Also on the tuning...I know it sounds scary but with a good tune, the engine will run cooler, get better mileage and not work as hard. Really though, I understand not wanting to harm the transmission but you don't need to add a lot of power to have a good tune that will give you better drivability, i.e. Help with lower speed spooling!

I'm going to have to consider it. I'm going on a run in December. There are some ruthless long hills getting there. It's been OK with just the trailer, but I have a feeling the added weight of the camper is really going to slow me down.

Thanks. Some of the locations I go to can be a little rough getting in and out. I don't want it to be any more difficult then it needs to be. And then there's the fuel issue too. Lighter is better.

Nice camper. Does not look overbearing etc.

So I've been poking around the camper making sure there are no leaks and familiarizing myself with it. One of my concerns with this TC was the small amount of fresh water it carries, the spec lists it at 15 gallons. I uncovered the fresh water tank. I was thinking it looks kind of small. So I measured it. 13 x 9.5 x 19. I'm no math wiz, but I calculate that as only 10 gallons. Which really is not a lot of water. :M
I have a feeling if I call Adventurer they will tell me they include the hot water capacity (4 gallons) in the 15 gallon fresh water spec. Seems kind of shady to me. I guess I may have to carry extra water with me on the longer trips.

Manufacturers (not all) do this when they have already small capacities. 15 sounds right, 4 gallons in the water heater and another in the lines. Shady? Sure.

Mine had a 4" exhaust, BHAF mod, and was tuned. I didn't do the turbo wheel upgrade but rode in trucks with them...big difference. I also left mine on a 40 horse tune and yanked around a 10k toyhauler and TC for years. No issues!

Mike take a look at Riff Raff diesel better turbo wheel choices :)

Nice setup. That is tyoical for the 7.3 powerstroke...they don't spool quick...try a wicked wheel and some minor tuning.

I'm considering a new turbo wheel, exhaust, which it needs anyway and maybe something on the air filter side. I'm really trying to avoid a tuner. The truck has been 100% reliable and I'm concerned about fooling with it too much. Also I don't want to add a ton of power, I don't want to put the trans at risk either.
