I would be exhausted too if I spent 1.5 hours setting up unless we were there for a week, even then, I could do it in 30 minutes. You don't say if you have jacks, but even running up on blocks doesn't take that long.
Realistically, disconnecting my toad takes about ten minutes from start to finish and I usually do that in the registration lane while my wife does the registration. She walks out, hands me the campsite number and jumps in the toad and follows me.
I back into my site, connect my water and electric, no sewer if just overnight, pull a floor mat out of the bay for the front door and go inside. I air down, level, turn on satellite and extend slides. I wash my hands, get something cold to drink and go outside and pull out a chair and relax. From registration to sitting down in the chair is under 30 minutes.
A tip I tell many.....buy the brass quick connects for your water hose and attach on the RV side. You won't spend time trying to thread a hose on each time. It also saves the connection from constant on and off.
