I just purchased a Photobackpacker Kelty P2 pack for a hiking photo clinic in a few weeks. Fits a 4x5 field camera, 3 small/medium 4x5 lenses, a rolleiflex, an F100 and a couple lenses for that. It's awesome. If you're just working out of a car, you could probably use any frontloader pack and buy photobackpacker.com's cases appropriate for your gear. When I was looking at the stuff I was more focused on the pack than the cases, but now that I have the equipment I would have to say that the cases are just incredible. Highly recommended for any pack.
