For a fixed height bed rack, I like the EVO bed rack.
For an adjustable bed rack, I like the Road Armor unit.
There are a number of tents that are good. For the traditional "pop-up book" style tents, it's hard to beat ARB for quality. But I've done a couple ROAM Adventure tents lately and they seem to have the same quality as ARB at a better price. For a hardshell tent, James Baroud is the top end, but they are very expensive and have big distribution issues here in the states.
For canopies, we sell the RSi Smart Cap canopies and though we get really good reviews on them, I haven't installed one yet, so can't say from a personal viewpoint. I have messed with ARE canopies in the past and they are very nice.
The only canoe mounts I've done are the Rightline foam pads.
