F550 thoughts?

Thinking about a F550 chassis motorhome with the 6.7 diesel.

I will need to tow around 6k lbs and will go over Raton and/or Monarch Pass frequently.

Thoughts on power?
Ride quality?
Fuel economy?

Thanks

    From what I have read it can be serviced from the top. If the engine has to come out it comes out the front

    Unless the OP edited the original post, the motorhome is not unnamed. It's an F550, which has hydraulic brakes, and the GVWR and GCWR figures are readily available online.


    I don't have a clue as to what he's talking about either. Post hasn't been edited

    We have a Thor Magnitude with an F550 chassis and love it. It has the power to tow my Wrangler 4XE with no problems and I get just about 10 mpg while towing. The Wrangler weighs about 5500 pounds. You should have no problems on any hills that you encounter. My Magnitude is 19500 pounds.

    The chassis numbers for GVWR and GCWR will tell the tale on that.


    LOL. It’s a pickup truck chassis, they have never made one with air brakes, and there is only one F550 chassis so there is only one GVWR and GCWR number, no options.

    We have several of those chassis (albeit with flatbeds or dry van bodies) and with a cheap plug in tuner they are a very spirited drivetrain, even with a pretty big load on. Even empty they have a very civilized ride. The older one a have here as a farm truck has a *far* nicer ride than my cousins Dodge 350 does.

  • Should be fine driving it with air-brakes and a regular operators drivers license.
    Under 26,000 lbs , non- commercial privately owned vehicle.

  • That's potentially a big rig.

    Should have enough power for reasonable hill climbs/descents. The chassis numbers for GVWR and GCWR will tell the tale on that. You're probably not going to win any races with it.
    Ride quality is pretty subjective, bad roads, bad ride, good roads, ???
    I wouldn't worry too much about fuel economy on anything that large. The old saying,"if you have to ask MPG, you're probably in over your head". (paraphrasing)
    Engine braking on one of those bigger rigs would be a benefit, particularly if you're climbing and descending grades over 3%-4% - safety factor?
