Chaparral 390qsmb Coleman Grill Connection

We didn't get any type of hose to connect the Coleman grill that comes with our RV to the LP quick connect that's just under the grill. I've heard the connection wouldn't work anyway because the LP tank is regulated as well as the grill itself. Is this correct?

I don't know of any FR brand that has a factory Coleman grill.
Mainly because their quick connect propane hose is low pressure and Coleman grills are high pressure.

Mine has a Coleman grill that takes those small green propane bottles. I went to Lowes and bought one of these:

Shop Mr. Heater 12� Propane Hose Assembly at

and one of these:

Shop Mr. Heater Universal Buddy Fuel Filter at

I can use these 2 items and run my Coleman grill off of a full size propane tank. They will drop the pressure down to a usable level.

I'm with Dan... I don't believe any FR models come with Coleman grills.
It must be something the dealer threw in.

Without knowing the exact model grill you have, we are all just guessing as to what you need to connect it to the low pressure port on your camper.

Why not go back to the dealer and ask how they expect you to connect it?
If your dealer is worth anything, they will make sure an accessory they provided is usable.

Is this Coleman Grill of the "Road Tip" variety?

We have the same setup on our 390. Hasn't worked correctly since the day we bought our 5er. Had it back in to the dealer for some warranty work this spring. They tested it and thought it was a bad connection at the grill. Ordered a new one but same issue. It's either on (albeit low) or off. The knob will not adjust the flame as it should. Will not get hot enough. Between the regulator at the Coleman grill and the regulatory at the tanks, I don't expect it to work correctly. Can't have two regulators in the line and expect it to burn hot. It works fine when I hookup a standard 1 lb tank. I don't know what the fix is but it's going back in this fall for some additional warranty work and that'll be one of the listed items. We'll see what they say. Keep me posted on yours.

My grill goes from low to high and it will hit 450 degrees easy. I cook all my meats at 400 degrees and then crank it up to burn it all off.

Not sure why you have an issue.

I threw away all the green bottles and bought a one gallon refillable propane tank, a three foot propane hose and regulator. This set up works great with my Coleman grill and I have the option of placing it any where in camp I want.

Here's a pic of the Coleman grill that came with my 390. It is definitely "factory" as the pull out rails have a bracket that fits the legs of the grill to keep it in place.

The issue with using the quick connect and an adapter for the grill's regulator is the trailer supply at the quick connect is regulated (low pressure) and the valve with the grill is for a high pressure 1 lb bottle.

I haven't found anything that will let me use the quick connect and screw it directly to the grill. The quick connect extension hose I have has a ball cock valve on the end. That will act like a valve, but I haven't found an adapt that will screw into the grill.
