I would get a large rubbermaid container with a lid(fairly sealed) I would place your live rock in the bottom, then build and eggcrate platform above the rock, then build eggcrate cubicles for each coral(easy to make eggcrate cubuclies, cut eggcrate with pliers, zap strap together)cubicles could be a couple levels high if need be, place airstone in bottom level with liverock, also place heater below with liverock, preferably 1 powerhead with liverock, 1 powerhead on coral levels. Large airpumps usually consume 5watts or less, powerheads are minimal, smaller ones use less than 25watts I believe, a 150watt heater should be plenty, a 300watt inverter would handle the load no problem. With a setup like this you will have no problems even if it takes a couple days to get to where your going, always good to bring some ammonia nutralizer. Inverters are handy to have so $100 is well spent if you dont have one already, rubbermaids are cheap and most people already have some lying around, eggcrate and zap straps are cheap...
If I had to move my stuff a long way its how I would do it
