I'm considering buying a new 2013 Monaco Knight 36' with the maxxforce 10 rated at 350HP and 1150 torque. I plan to pull a 30' box trailer at about 10K lbs. Any pointers? What rep does this motor have? And cooling it is a rear radiator.

I think in the end you will have wished you went with a DP. Just my 2 cents. If you PM me I will be willing to set up a call to you and maybe help you out. Good luck and keep us posted.

That seems to be a heavy load to pull with that motor. I have to believe the 10K is pushing the limits of that MH. At 350 HP with 1150 torque, I would really check the specs for towing 10K trailer. Remember the tongue weight of the trailer lowers the CCC (Cargo Carrying Capacity) of the MH.

I also think you are close to the max allowable length here. 36 foot MH, tongue length and 30 foot trailer. I believe I recently read that the max allowed length is 70 feet.

Personally, with 1150 lbs of torque, I don't think the engine will have any problems with that combo which might be 40k lbs on the road. Honestly, I wouldn't be surprised if that engine (obviously not with the same chassis) could handle a 70-80k lbs combined weight.

We have a 2012 Knight with that engine and although I can not comment on pulling 10K lbs we went from Florida to Nova Scotia and back last year towing between 4 and 5k lbs and we didn't even know we were pulling anything. I think this engine has a good rep. and seems to have ample power. If you buy it good luck . I think they are great coaches....Alan

According to Monaco the GVWR is 36000 pounds, GCWR is 46000 pounds, which tends to indicate the ability to pull a 10K pound trailer, except that they do not give a hitch rating. Also the GCWR would include all people, equipment household products, etc, including everything stored in the basement. This just sounds like you will go over the GCWR for the setup you are describing. Overloading is not a good thing, even temporarily.

Well...the passengers and cargo are already accounted for in the GVWR. Adding the towing capacity to that is what determines GCVR.

Also, the Maxxforce 10 from Navistar should have plenty of power for a 36' motorhome IMHO.

I too have a 2012 Monaco 36' with the MaxxForce 10 engine. I pull a 6500lb trailer often up and down mountainous roads (400ft to 7200ft and 7% grades) with no problem. The unit is rated to pull 10,000lbs and in my opinion you should have no problem.

Matchayan · 02-19-2013, 09:30 AM

I have a 2011Monaco Cayman[Knight] 36PFT with a 340hp cummins I would not be able to pull that combination but with the torque you have in thwe 2013 and if it is an Allison 3000 not a 2500 you should be fine. I agree with the other posters that you will be maxed out on your weights.
But what would concern me more is that these coaches are rear end heavy and do not handle well if you ad that amount of hitch weight and 30 ft of trailer IMHO you will have a white knuckle time of it in the least bit of wind.I pull a 26 ft riverboat at about 5000lbs. if a wind comes up on a freeway it is not a pleasant experience. I would suggest looking at a 40 ft Knight, its wheel base is 4ft longer and much more stable. As far as the coach goes we love it, but hopefully you are aware that Navistar , Monacos parent is financially in trouble and Monaco is for sale. That could present problems down the line.

I concede part of the GVWR includes the household items, etc, but most subtract the weight of people, and fluids in fresh water and propane tanks. See the tag from one MH:

The CCC is what we are talking about here.

michelb · 02-19-2013, 12:29 PM

Confirm it with the dealer / Monaco but I really don't think you'll have overweight issues with the 36' Knight. It's the same chassis as the 40' Knight and you'll probably be several thousand pounds less. Even the 40' at 36k GVWR probably has ample CCC.

Some older DPs do have weight issues but those often only had 24k-30k GVWR (e.g. a 05 Discovery 39L is 39' and has 4 slides but only has 28k GVWR so I wouldn't be surprised if it only has 2000 lbs CCC or less).

Dennis_K · 02-19-2013, 03:02 PM

In my 2012 Monaco owners manual it states the following:
GVWR 33,000
GCWR 43,000
GAWR (Front) 13,000
GAWR (Rear) 20,000
Hitch is rated for 10,000

I have not weighed my RV yet so I can't say how close to the 33,000 it is.

There seems to be some confusion over terms here. This is taken from the Workhorse manual:

GVWR - Gross Vehicle Weight Rating:The maximum weight the chassis was designed to carry including cargo, fluids and passengers. This does not include the weight of any item being towed but does include the tongue weight of towed item.

GCWR - Gross Combined Weight Rating:The maximum amount of combined weight of the chassis including cargo, fluids and passengers as well as any item being towed (trailer, boat, vehicle, etc).

I think the label you posted muddies the terms a bit by showing the equation to determine CCC.
