I just bought a 75 gallon set up that was approx 20-30 miles away. This is what we did. Well, I paid the guy $75 to bring it and set it up for me, best $75 I have spent in ages.
He took out the water and put the water into 2 garbage cans with tight fitting lids. The LR went into a couple 5 gallon buckets with some water. The LS went into another couple 5 gallon buckets. The fish went into their own 5 gallon bucket and rode up front in the cab of the truck. I think it took 2 trash cans and 5 buckets to move everything, but it was pretty straightforward. I would have preferred they leave the LS in the tank but perhaps it was too heavy that way - he said there was 300 lbs (???) in there.
Edited to add: My fish stayed in the bucket for 24 hours before I put them into the cloudy tank. It took approx 3 days for the tank to settle and clear.
Hope this helps somewhat!
