Call a gas company to make sure. Not sure if you can adjust that valve or not if you read the description it states that it will only work after a certain serial #. That tells me they made a change. I would call Suburban and give them your serial # and ask before you install it.
10.5 works. all the appliances have secondary regs now. you see one at the range, its a 10.5 as well. the gas valve in question has a 10.5 reg as well...

Sorry but a secondary regulator means squat. It depends on the primary. I do not have a secondary regulator on my furnace, W/H or Refer. You never run to regulators in a row. There is no reason to. Your gas valve servers that service. Unless your calling that a regulator?

To regulate the propane pressure, your RV has a two stage propane regulator. This is a component that fits between the tank to the rest of the system, and it takes the fuel coming out of the tank at a high psi and brings it down to a manageable flow. The first stage lowers the pressure to around 10 to 15 psi from its much higher number, sometimes 250 or more. Then, the second stage takes it down to around 11 water column inches, which is the right flow for your RV’s appliances.

This statement was taken from the propane suppliers. Unless the OP serial # is what I posted from suburban it will not work correctly. Will it work yes, but your pressure that it is designed for will cause problems down the line. I have just went out and looked, I do not see any secondary regulator at any appliance. Please post a picture of this so I know where it is buried being all have a copper line exposed to the gas valve's only? Thank you I love to learn new things. Even my side kick BBQ there is no secondary regulator as you claim.

Personally, I would get it repaired at an authorized service center.

You were very lucky as you could have lost the camper (and perhaps a life).
Gas appliances are nothing to fool with if you are unsure of your skills in this arena.

your lp tank is stamped 240...your reg will not see 250 plus. pop your range top...see that little reg there? ive noticed a little reg built into later gas valves as well...

If it would make you feel a little safer you can go to your local plumbing store and get some wire insulation . I have used it in propane service work many times when replacing glo bars in ovens and water heaters where the wires are close to the burners . the other post are correct you can not rebuild the gas valves . If it shows signs of fire it should be replaced .

Tires are stamped with a max., but that doesn't mean they won't see more. Same with LP tanks.

Gone are the days when I could rebuild the gas valves......but I would check, double check, and triple check for leaks and performance before i collected my money and left the customer. I wouldn't have wanted a law suit or to kill somebody. I'm glad you can't get rebuild kits anymore. Just bite the bullet and replace it. BUT, if you aren't experienced with such things, have a professional service person do it. There's too much at risk. It's worth the extra dollar.
