R-pod 179 newbies. Need help

We are finally getting our 179 ready for our first trip later this month. Had to do some unexpected repairs because a large pine branch fell on the pod while we were away, so our pristine trailer is no longer so. May have a little bit of water damage, but nothing serious - fingers crossed. After plugging in the power and starting the fridge on 120v according to the manual, we have no coldness after 24 hours. All the lights are on but nothing is happening. Any suggestions - am I missing something? Just switched to gas and I am waiting to see if that works. I hope it is something simple and someone out there can set me straight. Thanks in advance.

Thanks for the quick response Stephen. I have it set at max. It is plugged in and power is definitely available. I'll leave it running on gas for a while and see what happens. It is about 50 degrees outside - and inside.

Thanks for the input. It has been running on gas since yesterday afternoon - about 18 hrs now and has not cooled at all, so no luck there. In fact it would have been cooler inside if I had left the door open - it was frosty here last night. The gas is burning but no cooling inside. looks like it will be off to the dealers tomorrow. I don't think I can do anymore. This thing is only a year or so old and the previous owner assures me that the fridge worked last time he used it? Are these really so fragile that they break down just sitting around? How critical is leveling? It currently is very slightly - maybe and inch - lower on one side in my driveway. Could that be a factor. If it is how do they work when you are on the road?

Whoops....I see the computer changed your name and I didn't notice....apologies.

Well....thus far we are without snow although it is all around us....even South Dakota got a blizzard. Just sitting without the fridge operating won't be the cause.  We've always been told that operating the fridge when the units aren't level will eventually cause them to stop working.  We've always been pretty diligent about leveling our Pod. Is this the cause....I don't know but if you've done the tests that StephenH suggested then the next stop is the service bay.
