I've got one but I'm greedy and don't really want to come off of it as it is my second X and got this one because i missed the old one. Good luck the are hard to find.
what are you painting just the underside of the bed and frame because all undercoating stays a little tacky and it will come off very easily. if its that flat bed in your avi that you are painting i would herculiner the the whole flatbed
the 5 gal buckets and 2.5 gal jugs are really easy to poor but the 35 gal drum you would want to a spicket type valve to thread in the hole cant remember what they call them and i use to work at a shell dist. co. free fluids are nice
