I have a 2000 Coleman Bayside with a high pressure outside stove and low pressure inside/stove. I have two propane tanks; current factory setup goes bottle->high pressure regulator->out to high pressure stove->low pressure regulator-out to low pressure stove/inside. I would like to add an auto changeover but the units I find like this https://www.amazon.com/Exceisior-Excelaflo-Automatic-Changeover-Regulator/dp/B00KPR9Q30 all have a regulator attached to the changeover unit that look like the low pressure regulator I have at the bottom of my current assembly. So, if I replace everything I have with the new unit, it seems I won't have any way to hook up my high pressure/outside stove; if I put the new unit on top of the regulator I have at the bottom, I would have two low pressure regulators in a row. Help.
