Desert Captain,
Good Luck on your trip. I envy you. We probably won't be leaving the driveway until at least June...if even that. The rig really hasn't moved in the past 2 years or so. Wifey & I have been sleeping in it most nights, though, so most systems are being tested occasionally. And yes, it's expensive to run the electric heaters...but I've become an expert on how to keep the water flowing in that rig down to sub-zero temps! ;) We're giving the kids practice to live in the house on their own! LOL
Safe travels!!!

Also will change my tire psi.
Please take their entire recommendation to heart. You don't just "change" the tire pressure. You need to weigh the rig as loaded ready to travel. Individual corner weights if possible, but that's usually not too easy to do. The next best is to get each axle weight. Then use those weights to find the proper pressure from the tire manufacturer's website.
I don't believe you've informed us of the chassis or size of your RV.
Please weigh it first, then adjust the pressures, though if you're the typical E350/E450 Class C, having the rear tires at 80 psi seems to be a common requirement/recommendation for the longer (28') rigs. But it really depends upon the size and weight of your rig.
Good Luck,
