As you read regularly on the forum, you will find that some things mentioned in this thread are controversial. For instance,
Problem is, with just ordinary valves, it can be hard to check and inflate your rear dual tires.
Many of us are happy with ordinary rubber valve stems as long as the ones on the outer duals are long enough to be reached with a dual wheel double ended pressure gauge. The gauge must have a straight end to reach the inner valves.
A Fuel Stop checklist is good too - Any LPG appliance needs to be turned OFF.
Some say there has never been a filling station fire caused by an RV fridge so no need to worry too much about it. It certainly is required to turn off the propane at the tank when using tunnels, ferries and underground parking where propane (heavier than air) can accumulate from a leak. As pointed out, be sure to turn off the fridge in these situations in case someone else is leaking propane so your igniter isn't sparking.
The fridge stays cool for quite a while so you won't melt your ice cream if you have the fridge off while doing a little shopping at a store with unlevel parking.
