Empty tank, right down to the sand. Is it rr? Bottom drained. If so, protect connections during move: we set ours on the stand in the truck, strapped down.
Board all corals and fish if you can. A fish store in the place where you're going might agree, in return for your business. You have to hope they don't accidentally sell one of your fish.
Bucket all live rock and inverts with adequate circulation. Get them over to the new place early if you haven't been able to get boarding space for them.
Don't believe 11 hours. It will take longer.
Get new sand. Have it with you. Wash it beforehand: you won't be able to find half your gear.
Take enough salt water or go over to the new place the night before the move and get it stirring.
Set up asap, abandoning spouse to do other jobs...get the eggcrate protection down, get the rock down, get the new sand down and get the water in. For your live rock, it MUST be salt water from the get-go. Plan on a five day cycle.
Your fish/inverts will be effectively in quarantine for the next number of days.
I did a cross-town move with nearly this number of moving parts, and on arrival, there was a problem with my sump, which delayed the setup for a week and a half. I was in a mess. Expect things to go wrong.
You might take advantage of this move to increase that sump size to 30g, which would allow a 20g fuge. Or to make any other changes you wanted.
