I carry enough fresh water to use on the road for stinking up the camper and washing my paws after.
We run with the propane tanks on and fridge running. Keeping my beer cold is important.
I check tire pressure before a trip and maybe once while milling around the campground. Mostly look for any tread bulge that indicates the possibility of foul language down the road.
I check my oil every 5k miles whether it needs it or not.
We've spent many nights in our properly leveled for towing trailer still hitched to the truck. I do unplug the cord to prevent gremlins traveling up the cord into the truck's electrics while plugged into shore power.
We stick with Rack and Pinion slides. Never had a problem with sticky valves, leaky rams or stretched cables. My dad used to like to ride the slide. He was old. I'd let him ride it again if I could bring him back.
I dump the pooper tank at the campground. Two gallons in with the blue before every trip. I'll probably break our new one in on the way home from the dealership. Happens when I get nervous.
The ones that tickle me are the F550's towing a Casita with a Hensley Arrow. :B
