Huge thanks to the last two responders, I had no idea that the GFCI tripping was likely a neutral/ground problem, this allowed me to test continuity between the neutral bar and ground bar and i found that there was an intermittent short, pulling wires out one by one isolated the water heater circuit as the problem. I'll keep looking for where the short is occurring but with LP i should be able to be fine without an electric water heater. The best part about it is that I learned something new. Thank you all so much!

Happy Camping!
