Pilot light help? 97 Coleman Cheyenne tent trailer

[Chappyland]

So my wife and I bought a 97 Coleman Cheyenne Trailer this year. This is our first time owning a trailer. I can't figure out how to get the pilot light to stay lit for the fridge in the trailer. I can get it going and it'll stay lit for about 2 minutes then shuts off. The stove works fine both inside and outside of the trailer. Can anyone help? Also, maybe a dumb question but will the furnace run off the propane as well or do I need AC power?

It'll take several attempts to purge the system on the fridge. The furnace is DC power, and does run on propane.
