not sure if this is the best place to put this or not. i want to be able to take 20-30 (maybe more)gallons of drinking water/general pupose water/fresh water with me on a week long trip, dont want to put it in the back, top of, or in the truck. i have been thinking about putting a 2in receiver hitch on the front of my truck, then build a little tank or buy a tank to hang off the front of the hitch (think 60's gasser style...lol) anyway, what kind of creative potable water solutions have you guys thought up for expo travel. i would love to see some pics. thanks!
