I don't think I would enjoy camping if it took 1.5 hrs. to set up. We pull into a campground, connect electric and we're done if it's just an overnight stay. The toad stays connected if we have a pull-through site.
Our new coach uses holding tank water only for fresh water so there is no need to connect to shore water unless we are low. The holding tank (we have a combo for grey and black) will only need to be emptied if approaching full. So, our setup time is really not long (20 min. max).
Now, if it is spring/summer we will set up more outside (chairs/table/grill, etc.). While I'm working on the outside, my co-pilot is setting up the inside and generally, 30 minutes for both is plenty of time.
So, for tips on making it shorter is to do less. Do you really need to do all the things that take 1.5 hrs.? Checking for limbs? How long does that take? Usually, there are no limbs or obstructions in most parks.
Safe travels,
MM.
