Hello All. We pick up our 260RD next week and it'll be a week or 2 later that we head out for the first time. This is our first 5th wheel - we had a Class C for 3 years - and I'm confused on the unhitching sequence. I'm assuming the first step is to unhitch the truck. When do you plug into the power post, before or after leveling? At the other end, hitching up, when do you disconnect the power? Another question; how far off level can the rig be before I start the self leveling process? At times on my class C (manual leveling), I would raise one or more tires 6+ inches on blocks to get level. Using blocks and the leveling system on the 260XD is there a limit to how unlevel the ground can be? Thanks for the help, John
