Congrats Dvitale300,
Showing a Saint is not easy. I have a show Bernese and he travels with me in the cab of my new Ram Laramie, fold flat floor in the rear. I would not travel with him in the TT because I need someone to talk to on the long drives. Not being able to lower the tailgate is also a bummer. Is there room to move the tanks back and then move the tongue jack back enough to clear the tailgate? Might need to do some welding to make it work. Think outside the box. How close is it to clearing? To help with the dog hair some I cover the entire back seat area with a sheet and take a few along on longer trips. Use the dog blower to blow out the truck. If you have too much dog for the cab you'll just have to get a class A MH like all the big dogs at the shows. Do you have your X-pens mounted on the back bumper yet?
