We have a minivan that we've outfitted to become a camper with a sleepdeck and room underneath for all our gear. This is glorious and easy as pie...as long as we don't have a canoe on the roof that makes opening the trunk impossible. If we can't open the trunk, we are relegated to crawling around under the deck, pulling lots of things out to get to the one thing we need, and just all around frustration. Does a canoe rack exist that can raise the back up when you want to get in the trunk and then lower again when you're driving to save gas?
