Adding on board Generator

Looking for advice on type of on board generator to purchase.
Want to run 2 15k ac, 2 tvs and satellite. Also do most generators have fuel tank or just add tank?
I have a Champion 3100 that I have been using but want something bigger and more quiet. Looking for someone who has a onboard generator.
Thank you

  • I prefer my 5500 LP propane Onan vs. gas in my 5.er simply because of the carburetor issues with gasoline. LP is clean and doesn't gum up.
    For this reason my LP genset has been very reliable.
    I am just an occasional user. I overnight, stop for lunch,etc.
    If I had plans to run genset regularly for multiple days, I would most likely want something other than propane.
    However for the occasional, short term user LP is fine
  • You have to derate the gasoline generator to about 80% capacity when operated on propane. It will burn through a 40# propane bottle in short order, so be prepared to do a lot of propane swaps if you run the generator on a full time basis.

  • We have a 14 LM Savannah with the gen prep ,i installed ahonda 3000 eu in the front bay .It easily runs 1 air cond washer dryer at the same time and is very cheap to run,20 hours on a couple of gallons of gas.Yamaha has a 4500 inverter gen in gas that might fit.

    Do you have pictures how you ran the exhaust, out of there, and how you vented it. I was under the impression that those 3000 EU had to be in the open ,not designed to be in a enclosed compartment ??
  • I POINTED THE vent exhaust out the the open door .IT runs cool with no issues.There is a vent/exhaust kit online for it.I fill it using a milk jug,but do have a 12 volt pump ,just too lazy to use it.I have 250 watt solar as well ,2 550 rolls batt so just run it 4 hrs a day if dry camping to top up.
  • If you have a Diesel truck I would get a Diesel generator and mount it in the bed of the truck and not have to mess with propane or gas. It would also do away with the vibration of the trailer when running and cut down on noise.

    The main disadvantage of having genset mounted i the truck is the RV itself is not always self contained.
    If the truck leaves the electricity leaves.
    May not be a big deal all the time. But on occasion it will create an issue.
    Want go into town with the truck there goes the electric. If it's hot out there goes the A/C.
    I prefer to have the RV independently self contained.
    My RV is parked in the back yard, We can just stay in it as long as necessary no truck required.
    We have stayed in the on short notice due to power outage, hurricane, storms etc. Its nice to be self contained when you need it
  • I did the same exercise a few years ago, spent a lot of time working on the various details and came to some conclusions. Propane was not efficient enough, diesel was too heavy, a 5500 Onan plus fuel tank, sheet metal, plumbing and electrical put me at about 6k and a lot of time. So, I ran a cable from the shore power connection to the front and installed another shore power plug next to the front storage door. I built a weather proof enclosure and installed a Honda 6500 with a remote start in the bed of the truck with a 20gal remote tank, a 15' cord makes the connection and can stay connected full time if your lazy (don't know about running it while driving, never tried.) I've got about 800hrs on it and it works flawlessly rain or shine and I have plenty of power to run whatever whenever, no vibration no noise.

    Your correct, I was thinking how I use a generator. My 5er and TT have built in Onan's and fuel tanks. I mainly use them for stops on the way and I'm connected to the truck anyway. Most of my destinations have power. So while a truck bed generator would work for me it might not work for others.
