When that is all done, I hit the level-up system and raise the unit to take it off the truck and once it is clear I hit the auto level and level the unit. The last thing done is bringing the slides out. Then I hook up the water and sewer line if needed and we're set to go!
Your Class A neighbor was told wrong because by putting the slides out first and then leveling the unit will put more stress on the slides than leveling first and then putting the slides out.
