When we pulled out of our dealer in March on delivery day, with our new MH and first RV, the Jeep was hooked up 4 down and we were on our way to our first weekend shake down. It wasn't until August when I took it into the dealer for the first 5,000 mile chassis service and a couple of warranty items that it was driven on the road without the Jeep hooked up...........
It's just not a big deal, other than being cognizant of gas station layouts (in a gasser).
