Has the unit been in storage? Have the tank valves been turned off?
If either of those are the case, it's an easy fix, just turn on the propane valves (VERY slowly!), then go and light the stove. It will take some time for the stove to light because it's typically a long way from the tank valve to the burner valve. Let the stove burner burn on high for a minute or so, then try the WH again.
If you've confirmed that the propane tank valves are open, and you still can't get the stove to light, then you have a different problem. The tanks have safeties in the valves, if you open them too quickly, they will shut off. The "pigtails" also have safety valves in them; same thing if you open too quickly, they will shut off the flow. I've even had them go bad on me and needed replacing. If you've opened the tank valve very slowly and still get no flow, try closing the tank valve, disconnecting the pigtail from the tank and rap it lightly on something hard, that could cause the safety valve to reset. Reattach, open the tank valve slowly and try again. If still no glory, it could be a defective regulator. You could try tapping on it to get it to work. I don't know how to test a regulator because I've never had one go bad on me, but I know it has happened to others.
If you can get the stove to light, but the WH still doesn't light, you probably have a WH problem. Make sure the area around the propane supply in the back of the WH is clean and free of debris. Critters like wasps love to build nests in those areas. Install bug screens on your vents, and I've heard a simple flea collar for a dog helps keep critters out of those compartments.
Have you tried to light the WH with a separate flame source? Have an "assistant" trigger the WH, listen for the gas flow and try to light it with a lighter (one of the long ones maybe? Just in case...). Maybe it's just the pilot that's not working right?
Sounds silly, but is there 12V available? The circuitry on the WH works on 12V DC power. If there's no 12V, it's not going to work. Make sure that your battery is charged up and all your 12V is working properly. Try plugging the rig into a 15A household socket, JUST to power the converter and put a charge on the battery as well as make 12V DC available through the converter, don't try to run high draw appliances like the air conditioner this way.
A lot of this stuff may sound kind of silly, but these are all the things I would check first because they're easy. Oftentimes it's the simplest explanation that solves the problem.
