Couple of ways to do it:
Fill tank/raise the front of the coach= drain with coach headed up hill.
Yes, you can use your hand over the fuel inlet with an air chuck to slightly pressurize the tank. It should not take over 2-3 PSI to raise the fuel above the level of the filter.
Relocate the filter lower on the chassis.
And, most importantly, with a clear plastic bowl on the primary fuel filter (fit a filter with one if you don't have one now) all you need to do is LOOK to see if there is water or debris in the fuel-- no need to open unless there is a problem.

A new coach. Having to jerryrig it for routine maintaince?
The real question is why does the OP have to jump through hoops ?
Sorry, I don't get it.

Not sure there is a perfect answer here-- at least that I have seen.
If level of fuel in the tank is materially higher than the fuel filter, fuel will pour out when the filter is removed.
If level of fuel in the tank is materially lower than the fuel filter, fuel will siphon back from filter to tank leaving XX feet of air to be purged.
The "right answer" IMO is to install the primary fuel filter low and with a ball valve at the filter intake. Shut off ball valve before removing filter.
Part of this, at least when changing filters, also depends on the engine and fuel filter setup. Example: On a Caterpillar engine with Caterpillar secondary fuel filter and MANUAL PRIMER PUMP, you can install the filters dry and use the manual pump to prime.

Does it have the electric fuel pump like Cummins that comes on when the ignition is turned on?? If so have someone turn the key on while you open the drain. It should have a water sensor that will tell you when you get water so their is really no need to drain it.

Just do as i do and run the engine and drain a little fuel at the same time.Pretty simple

I think everyone is making this more difficuilt than needed. Look on top of the filter base and you should find a bleeder port / screw. Loosen this screw slightly while opening the water bleed off. It needs air / venting from some place to get any drainage.

No, you don't want to introduce air to the fuel system on a diesel. If fuel level in the tank is higher than the primary fuel filter, fuel will run from tank and out the drain-- THAT is what you want.

If you open the water drain valve air will enter the bowel thru the drain also. I know I just done that. OP does not have a clear bowel so he does not see the air that has already enter the filter. If he changes the filter it will be full air anyway unless he has a primer pump. He most likey has more air in the filter now then if he breaks the vacuum at the top of filter. But I'm no expert and have not stay in a Holiday Inn Express
Also the genset will not be effected as it has it own filter and picked of tube, or at least it should have.

My thoughts are "What does the dealer say"?
