I need advice on what to do with my propane system. It has a spare tank in the front cargo, that I had initially planned to mount on the hitch with this one, and put an auto-switch-between (whatever they're called) thing on them. I just found out the other day that I don't have a gas furnace (no laughing ) so now thinking there is really no need for two tanks. Propane will be used for fridge, hot water, and cooking only. Currently, there is a single stage regulator, which I know I have to replace with a 2 stage. I also have no use for that meter thing on there and want to just get rid of that. 1) Can someone give me advice, preferably with links, of what I need to buy to make this right? And step by step directions of where everything goes. 2) Should I go ahead and mount the second tank, or just leave it with one? 3) Shouldn't 2-stage regulators be mounted vertical? Or does it matter? I really don't like the way this single one looks and would prefer a vertical one. 4) See any problems I should be aware of in these pics? Thank you in advance for your time and advice!
