replacing a LP regulator- what to purchase ?

I don't know if it was meant for RVs but Rego used to make a 2 stage, auto C/O, 2 tank reg that could be tapped between the 1st and 2nd stages. I don't know if they still make it. I recently found a new/old stock Marshall RV reg like that and it has a nipple between the stages and I put a tee in there to run my RV grill which has it's own reg. There's 18 psi at that point and it works great! Maybe try an LP distributor. You can use a new style RV 2 tank reg and plug one side til you are ready to use it and keep the selector arrow on the in-service tank. I don't think any of the new ones split between the stages.

I will be going to a vented cat heater and I have a newer Dometic fridge to install. The idea of having a tank mounted regulator for the extra tank I had not thought of thanks for that suggestion.
69 Avion you have so many hoses/fittings in that second pic I got dizzy ! I assume the quick connects are for when you tap in aux. LP items ?

You are correct. The Rego regulator will handle anything that I use with it including a 30,000 btu stove and an outside water heater.

The original regulator was an auto switch over Rego regulator. They don't make rebuild kits for them anymore, so I purchased a new Rego regulator. They are over $100 but they are much better built than the stuff you normally find on RVs.

You could plug the extra side until you found an external tank to hoo to it. The Rego regulator has plenty of capacity to run any outside appliance that you may normally want to run.

This can be a somewhat tricky deal or it can be really easy.

Do you have the original appliances in the Avion and did you notice if any of them have a separate regulator attached? What I ran into was that the appliances in my '71 Starcraft are set up for the older single regulator at the tank, not the newer two stage regulators that are more commonly used. If you have the same situation, you'll need just one regulator at the tank and any downstream output from the single regulated system will work well with a BBQ or other appliance that has it's own regulator (most of them).

You can make your choice as how you wish to plumb in an additional tank input. It will somewhat depend on how you wish to have that additional tank in use. It may be that having another single stage regulator at that additional tank and a length of hose tee'd into the system is the most convenient. That way, you can use the secondary tank to feed other appliances like BBQ's, lights, heaters (if only requiring a single stage) at any location. The use of quick connects may make it even easier and more convenient.

If you have more modern appliances, you'll need a dual stage regulator system and there are regulator headers available that allow for auxiliary bottles and additional appliance runs. Extend-a-stay/Sturgi-stay is one such header.
