I am sure you will get bucket loads of info, so I will tell you what we have. We had an onan/cummins 5500 gold, propane fired unit installed in the front compartment of our 3580rl. It runs the entire unit with ease, and uses about 2-4 lbs of propane per hour under full load. We are completely satisfied, and have had no problems. we did purchase two extra 30lb lp tanks and mounted them in our truck bed. Hope ya find what you like, listen to every one elses comments, then use some common sense and pick the best unit for your needs. God Bless ya, Al W
