Can I use 3 regulators in series?

I just bought a dual-fuel generator and would like to hook it up to my camper's propane system using the hose that supplies propane to the gas grill. The generator comes with two regulators at the propane tank fitting. Best I can determine, the first regulator is a dual-stage regulator, and the second is a demand-flow regulator. The camper's propane system has a regulator at the source tanks.
What is the best way to accomplish my goal? Can I run the generator with three regulators in series? Or do I have to remove one of the regulators? Hooking up directly to the propane tanks won't accomplish my goal.
Ideas/thoughts?

Here is a photo of the 2-stage regulators that came with the generator. Are You suggesting that

make sure what pressures are on the campers grill port.
some are setup for vapor and some are setup for liquid.
you can look at the grill and see if it has any regulators built in to the grill connections.

and you might not have enough flow off the grill port as most camper grills are under 50k btu.
unless it is liquid.

None of the ports on the camper are liquid, all are vapor.
Vapor pressure in the camper's propane distribution system is controlled by the regulator mounted next to the Propane tanks.
Grill has no regulator on it. It operates directly off of the camper's propane distribution system (which is regulated by the regulator mounted next to the tanks).

If the demand flow regulator/valve can be removed from the 2-stage regulator(s), then you can hook up to the already reduced propane pressure lines in your camper's propane system. The demand valve operates on low pressure LP gas coming in, and then meters the LP out to the carb by sensing carb vacuum (which is the demand).

If you have questions, post a photo of the Champion LP hose and regulators that came with the gen.

Your suggestion makes a lot of sense.
The demand-flow regulator is a separate piece from the dual-stage regulator. So, if I'm understanding you correctly, I should take the dual-stage regulator out and connect the demand-flow regulator directly to my propane distribution system (which is already regulated at my tanks). See attached photo. Thanks for the suggestion. I will do this later in the week and post my results. Any suggestion of where I can get fittings to help make this happen?
