We have 2 systems. When the DW graduated AirForce AIT at Goodfellow learning after how to fight the fire dragon I surprised her with the kids at her graduation. We drove from SW Ohio to Hurricane Mills Tennessee and pulled into a KOA. I pulled the Class C up on levelling blocks getting "close" to level. Rolled out only one of 2 slide outs. Total time 10 minutes.
As for our family vacations we have a system. We typically won't travel more than 5 to 6 hours a day. We have found that if we "grind" and pull in late we are just as each others throats. We typically have somehting like waffles/toast/biscuits for breakfast. Grab a shower at the shower house (all 4 can go at the same time) and get on the road by 10ish. We like to be in the "layover" spot NLT 1700 hours. Our old process was that I would sit in the captains chair, the wife would put the level on the floor and place the block around the coach as she thought we would need. I pulled up on the blocks and as long as we were no more than 1/2 bubble off plumb, we were good. Sent the kids to the playground. The DW would deploy the slides as I hooked the water/electric and cable up. Toad stayed on the dolly. As I came back into the coach she would have the stove/oven getting hot for supper and my favorite plastic cup full of Jack Daniels and Pepsi Max for me. I would enjoy some of Tennessee's finest export while I hit the auto program on the TV's and she finished supper. Called the cherubs back to the coach, had supper, dishes clean and kicked back watching prime time TV before bed.
I am not going to tell you how to make it faster because your DH has a system that he prefers. Trying to change him will only be stressful for him and very difficult should you get him off his program and something happen to the coach.
