Pap T, why keep the gray water valve open? I’d be worried about smells a bugs, vermin, snakes coming up from the sewer. Also, I use the water from gray tanks to help flush main pipe and hose after dumping black water. Could you provide some insight that I may be missing?
I recommend leaving all valves closed. We bought our Cruiser used and it was set up on a lot at a lake and they left the kitchen valve open all the time. Our first trip out when we dumped it took forever to drain the kitchen gray tank. The first half or so drained good then slowed down to a trickle. It took a good 15 -20 min to drain empty good thing we had full hook ups. got home and took a inspection camera and discovered there was a grease "dam" at the output line. A lot of soaking with hot water and grease dissolver - we used Mean Green and its better than it was .
So for us we leave all valves closed till we dump. If the gray gets full and your on full hook ups just dump them then close the valve. Also if you don't use or have a full hook up site they are closed anyways.

Thank you for the great advice. I noticed as I was shopping for supplies that Camping World was usually more expensive, too. I will work on the water heater. Good idea. Would it be a good idea to fill all the tanks with clean water and practice emptying? I used twice the gas hauling the trailer home than driving to the dealer. Oh well.

I zip-tie cabinet handles to keep from opening when moving. Also use kitchen towels to pad anything breakable in cabinets. Long yardstick sanded down (tapered) on one end helps for slide seals that don't always open to make a tight seal. Just run it up along seal to make sure they are out the way they should be when slides are out. I agree about keeping grey tank closed to flush black tank. I am set up full hook up year round at campground on NC coast. Only move when threat of a storm then have to have someone move for me. Have learned to do a lot by myself since losing my husband in 2018 but not moving the camper. I am good with the boat though. Happy travels.
