How do I install horizontal propane tanks in my Lance 1161?

I have only refilled one tank in the past 5 weeks.... thePlatCat vented heater has been used every night.... but it just sips propane and the very small electrick exhaust fan uses about 1/2 A per day

I must look old... people are holding doors for me.... and grabbing the propane tank and hoisting it for me (at least before we left and again a couple of weeks ago)
