To do this with some level of certainty, need to add up the appliances. The Marshall is what all the Sunline's I have been associated with used as factory supplied so I know that one was large enough.
From your furnace pic in the other thread. Zoom in and see it onthe label.This needs 20,000 btu's
The Atwood water heater calls out 8,800 btu. This is from one of my water heaters, yours should be the same.
For the range, mine calls out these 3 numbers. In case you have them all on at once.
Qty 2 rear burners at 6,500 btu's each = 13,000 btu
Qty 1 front center burner (master burner) = 9,000 btu
Oven burner = 7,100 btu
The range with all burners running = 29,100 btu
The fridge on gas. This is for a RM2652 and should be good for most of the fridges as they really do not use a lot of gas. 1,500 btu
Adding them up.
Furnace: 20,000 btu
Water heater: 8,800 btu
Range: 29,100 btu
Fridge: 1,500 btu
---------------------
Total with no reserve capacity: 59,400 btu
Since there is regulation tolerances at each appliance, there should be some reserve capacity at the regulator. I am not sure what factor they use for this, if we estimated 20%, then the regulator would need to pass at least 71,280 btu.
I would be looking for something in the 80,000 to 100,000 range regulator. Your furnace is smaller then some of the other larger campers so Sunline most likely put the same regulator on all of them even if oversized.
Hope this helps.

PS, what brand and model regulator do you have now? Got pic's?
