So far, I can fit everything I need with the FnR. I've been selective in what I have, but I've included the bird cage, the cat crate (only used if I need to leave the cat inside alone with the dogs), the portable grey tank and several water containers. My biggest issue is in the Durango. The very back has a couple quad chairs, hitch mirror, 12v cooler. The third row seat is Moose-dog's and I have leveling blocks on the floor. The middle seat is Bat-dog's and I have a couple blankets on one side. The middle floor has the bottle jacks, jump starter, air compressor, first aid kit, etc. The passenger seat has to work for Dog-bird in his backpack and The Cat in his carrier. The floor will hold my personal things, etc. Hopefully after a couple trips, I can fine tune things.
