Have owned coach's with different jack systems 4 style,3 point but if you own a Newmar with HWH system its all written here, like has been said do not want to twist the chassis frame can pop windshield or crack it especially a gas chassis much lighter frame than a DP chassis.
A Newmar coach each side rail of chassis is raised first and never lift rear tires off ground you will lose your braking grip to ground and jack system could collapse, jacks are for stabilization only.

On my HR Neptune the front jack must go up first, even a little, then the rears. This is a three jack system. Here is how it is in the manual.

"When manually operating the leveling system, always lower the front jack first.
The front jack acts as a pivot point for the chassis and reduces torsion stress on the body of the motorhome.
NOTE: In the event the front of the motorhome is high and does not require elevating, it will be necessary to raise front of motorhome a minimum of inch to allow jacks to act as a pivot point."

Reduces the stress on the windshield.

I have not had #2 happen to me but have read where that procedure was not followed it has happened. Maybe it will and maybe it won't but why take the chance of damaging the windshield.
I have cracked and had to replace one windshield . That was when I first bought the Seabreeze and didn't know the proper procedure for leveling. Now I am very careful when lowering the jacks, taking my time as I don't need another $1,650 bill .

Mine has a power gear manual system, and it says to lower the front jacks first and raise the front an inch or two, then lower the back jacks to level front to back. Then level side to side using the left and right buttons. Leveling side to side is done by the individual rear jacks. The front jacks are interconnected so when one side goes down the other side goes up correspondingly. This way there is no twisting of the frame, it merely rotates about the center axis of the front jacks. It is annoying to have to release all jacks if you overshoot and start over, but you can control each individual rear jack and the total level of the two front jacks so it isn't often necessary.

The PowerGear on my Tradewinds is a 3 point system even though it has 4 jacks. to prevent frame twisting the front 2 jacks work as one. Instructions state to raise the format of the coach 3 inches the adjust level with left and right back jacks, the lift in the front give the coach a pivot point

It depends on your jacks..... My Power Gear jacks the front pair act as a single uint, they are two jacks connected together so if you lower them half way and then use a floor jack to raise one, the other goes down.. (a 4 footed 3 jack system) Some RV's have only a single front jack (in the center) these simulate that system with 4 jacks.

With either of these systems I'd raise the front till it is a bit high (the automatics won't like doing that but Mine are now manual) then run the back jacks down and level side to side.

Alas, My control system is "Home brew" since the very expensive semi-auto system failed.
Home is where I park it!
