I think an Astro AWD with a pop top may fit the qualifications you are looking for. Having your own sleeping loft area above and having the dogs sleep below may be a nice feature especially if you have been out hiking all day in Alaska and the dogs are soaked and muddy. You can remove the sleeping platforms, which make the up the loft area, so you can stand up and walk around the entire back area of the van behind the front seats. I have been more than happy with my Astro since adding the pop top. Good luck with your search. I highly recommend checking out Overland Expo in AZ in May if you are looking for ideas for your adventure next year.
