I use my bike for commuting and transportation, but have recently decided to get a bike trailer to increase my payload. Since I don't have kids, I don't want one of those nifty trailers with kid seats. I want something that can carry sacks of groceries, a 50lb (and growing!) basset hound or other large items. I also prefer a trailer with two wheels rather than the one wheel model such as the BOB trailer. Also, the trailer will never be used off-road, so would like something with bigger rubber wheels for quiet and smooth running on paved surfaces.

Anyone have any recommendations?
Thanks
