Hey there was a vendor at Cruise Moab who stocks replacement gas tanks for the 100 series. I think they're 40 gallons? My understanding was you drop your current tank then bolt this one in its place, using all the same guts.
I never made it over there, was too busy BSing on the other side of the aisle all night... then I had to reel in a couple kids. Anyone know what I'm talking about? Or better yet, post up a link? I think the number I heard was $1200...
