Rockerga,
The totes I'm referring to are not the ones you see on the Campingworld site. They all look the same to me, too. I'm talking specifically about the 4-Wheeler tote-along by Barker. I don't know if they are available at Campingworld. These have big back wheels, thick and sturdy pull bar, maneuverable front wheel set, side emptying valve and all that jazz. Go to
http://www.barkermfg.com/product_pages/tote_alongs.html and see. They are further down the page than the original tote-along, and available in 16, 25, and 32 gallon sizes.
