Thanks for the great advice everyone!!
I am already pretty level while towing so it looks like I will be running the front jacks down to take some strain on the truck and the rears to help stabilize things and the slides out.
It also seems that we will use the onboard water tank to avoid hooking up to the campground water for convenience and just hook up the electric and dump the sewer if needed.
We are bringing the extra car along because of my wifes job, she will need the extra transportation.
Thanks again!!
