Solution to water loss while traveling
Many of us have had issues with the loss of water when traveling. Most of the tanks installed by GD have the vent port on the side of the tanks at the top. As there are no baffles in the tanks that I know of, water will surge (splash) around in the tank forcing water out of the vent pipe. On hills and side slopes water will also flow out of the vent port. The quick solution was to put a valve on the vent tube, but this could lead to a collapsed tank if not opened when you use the water pump.
My solution uses a commonly available air/vac valve at a high point to let air flow in and out of the tank normally, while still allow the use of a valve to stop the overflow from draining when in motion.
The ball drain valve is a 3/4" and all fittings shark-bite. The air/vac valve is also 3/4" and set about 24" above the tank. I ran the line forward and came up through the belly area of the basement by the door. It allows air to move in and out and has a bug screen built in. Its a typical air/vac valve used in drip irrigation systems, etc. So now when I fill the tank all I need to do is open the vent drain valve and fill normally until water runs out. The turn off the fill, let the tank stabilize and then close the valve. The air/vac takes care of the need to have air enter the tank when the pump is used and allows air to move in and out as water surges inside too.

Here is a close up of the air vac valve. I got the pex and shark-bite fittings at Home Depot and the air vac from my local irrigation parts shop, but HD may have something equivalent. So folks know when filling this valve will let air out of the tank, but if water gets to the valve (you left the drain valve closed) it will seal and not allow anything else out. So it is important to still have the drain/vent valve in place and open when filling. I added a note to my panel to remind me. Hope this helps.

But will it allow air into the tank during use. If it just jets pressure out, the tank may collapse when you take water from it if there is no way to get the air in. Just thinking here.
I did test it by driving around a bit and then draining the tank without the vent drain valve open. Air/vac valve worked OK and draining the tank is the max air draw that will occur.2018 Reflection 150 Series 220RK 5th wheel with 6K axle upgrade.

I went over and read your thread on the pressure relief. The 5 PSI minimum may be too high. Remember that pressure will be on all sides of the tank - that would be a huge force. Also this solution does not require pulling the belly material. Just attach to the vent line and go forward and/or up to above the tank . Trick is to get the air/vac above the tank somewhere.

Isn't there also a tank vent right next to the gravity fill port? My Imagine has that vent, , maybe they don't use it?

It's interesting that you say that come to think of it. Our last camper was a Sunny Brook, and whenever I gravity filled the water tank you could hear the displaced air and some bubbles and such coming back through this vent. Perhaps on the GD it's not connected as they have the overflow/vent coming out the bottom of the trailer.
When I gravity fill the tank on our 2970RL I don't hear or see anything coming from the vent by the filler.
