Thanks for all the replies, I guess it will be the $$$$ rotopax because I'll be using it on a Rt.66 motorcycle trip later this year and just don't want fuel leaking all over a brand new bike. As far as some of the replies; I have good options ; my 7x14 bike trailer, a 60x30 front rack, but I don't always take these,and won't be on this trip.I don't know why but my gen. compartment has a propane line inside but also a sticker that says "Do not store combustible materials inside". My taillights on my '13 F 350 prevent me from hitting the 2 1/2" stops on my TC, so I use 9x6x4 cork yoga steps against truck bed, so I have a 4" cavity that I utilize here, I just use my grabber to pull things to where I can reach them from the side.I miss my doors to truck bed in our old TC for storage, but not the old L---e. I also carry my gen. on back seat of truck on occasions and have never had "fume" issues. I've also thought about the Coleman White gas can like e few suggested. I sometimes use the rack that you hang chairs from on rear ladder with a platform attached, just don't like gas cans sitting in the sun all day while driving. Thanks again, K Mac
