I know some of you don't need it, but Sam's has a heavy duty hose cart; holds 400'. Like the $130 - 140 ones, but with pneumatic tires - very well built and only $69. I've never seen one like it.
Ive been looking for a hose reel. I have found a drum at a local gas company (drums their hose comes in on) I can have it for free but need to make a stand. I will check out your claims a sams. WAIT. What model is it so I can call and see if mine has it.
