A camper that size, I would not think about a 1/2 ton for anything but short flat trips. It will catch a lot of side wind. You will feel much more comfortable driving a 3/4 ton. Personally, I always carry my bikes on a rear hitch rack, but for your situation and number of bikes, the Outback seems like a good match. I've seen a couple of those and really liked the layout.
So now you need to decide diesel or gas.
Most likely gas. I'd likely be looking at a 2-3 year old truck, and while I can appreciate the benefits of diesel (parents had an F250 and traveled extensively with a fifth wheel) the $10,000 premium may not be worth it. Though I'd really have to crunch some fuel mileage numbers, potential longevity and convenience numbers, but that's still a big number to front when I'd ideally like to keep the initial investment down.
