Upgrading to a 10,000 reciever?

[palehorse89]

I have been searching the threads on here looking for info. on upgrading my 5,000# receiver on my Spartan MM chassis to a 10,000# rating for the purpose of towing a enclosed trailer. My Spartan chassis has a 10,000 GCWR, The Newmar sales Boucher states that it came with a class 2 receiver w/5,000# weight rating. I have read were some have had a weld shop "beef" their OEM receiver up, and others that have bought a new receiver rated at the 10,000#. Through out my search's I have not found anyone that lists a 10,000# receiver for a Spartan MM Chassis specifically, Where does a person find a higher capacity receiver that will bolt on to my Spartan chassis?
Any Idea's? Where does Spartan buy the receivers for their chassis? I think some of the late model chassis have come with 10,000# receivers(or higher) from the factory now?
My specs from Newmar = GVWR - 31,000# GCWR = 41,000#(I am under the GVWR)

Look at a Curt #15901 or #15903. The side plates are not welded to the tube from the factory, that is done at installation. They can be adjusted to the width of your frame and the excess cut off.

I bolted mine on w/ 4 - 3/4" bolts per side. It has quite a bit of drop, & that is why we connected it to the engine cradle. If yours doesn't have much drop that may not be needed.

The one thing I am having trouble with is finding one that will work , I have talked to a rep. at Curt Mfg. , not to much help. My receiver now is bolted on, by design, tight to the frame rails where it bolts on with no drop, my bolt holes on each frame rail are 6" apart, 3 on each rail. Can someone with a newer Coach(Newmar) with a class 4 or 5 hitch tell me the brand of hitch and the model number. I would like to find a close replacement in height as the receiver that is on there now comes through the rear flap and I don't want to have to change the flap if I don't have to.

A 10K curt hitch # 81400 is 28 inch between rails and 2 inch wide mount plates so total OD 32 inch and no drop.dead level
the mount holes are 6.5 inch center to center (3) per side
easy to drill more if needed
My frame is about 28.5 wide ID so hitch fits very nicely at 28inch body width

I have a Dutch Star on a Spartan chassis and installed a 15k made by Curt. It is a universal style not a direct bolt in. I had a removable link fabricated to connect the hitch to the engine cradle. Really did strengthen things up. My original 4k hitch was almost ready to fall off, but hidden by the dust flap. I have since towed 12k about 10,000 miles w/ no issues. Be sure to use a forged ball mount & a ball that will handle the load. Most any truck/ welding shop could do the work. I think my total cost may have been $500.

the 10K receivers are most certainly AVAILABLE as BOLT on from CURT hitches for Sparton chassis.and the OP chassis is rated for 10K
tow so a 10K hitch should be no problem on this 2000 spartan chassis
mine(Spartan) is good for 15K even though I have a 10K hitch
NOTE:this hitch was made to measure direct bolt on to sparton chassis
not a universal one

If the chassis can tow 10K, then upgrade, and ask the manufacturer why they did not put a 10K hitch on it to start with.

One thought... Naa. you will report if this is the case you will report if this is the case (Receiver size).

Even with the enclosed trailer, you won't be that close to max so GO FOR IT.

Called Spartan tonight, The receiver was installed as requested by Newmar for "car towing" purposes only, if I am under the chassis GCWR I am good to go to the class 4 receiver. As long as I stay within the numbers provided I am ok.

Thisis what you need.

Your question about a Spartan 10k hitch was asked before. Sounds like you are good to go with the proper setup.

I think I answered this elsewhere.. You said the chassis has a 10,000 CGVW rating (you may have put it in a different order) This means the Motor home and trailer, combined, loaded, must not weigh more than 10,000 pounds.

How you can do that and still overload a 5,000 pound receiver I do not know, I know I can't and my CGVW rating is 26,000.

Or did you mis-type.

As answered before, no I did not mis-type, so again for you......If you look at post #1 again, you are the one that changed the lettering around (CGWR) I did not (GCWR)
As printed on Newmars web site:

GVWR = 31,000 # (TOTAL THE COACH CAN WEIGH)
GCWR = 41,000 # (TOTAL COMBINED WEIGHT OF THE COACH AND WHAT YOU ARE TOWING)
UVW = 25,715 #(AS WEIGHED WHEN NEW EMPTY)
NCC = 5,285 # (ALLOWED WEIGHT TO CARRY ON CHASSIS)
When you subtrack the GVWR from the GCWR = 10,000#


I looked up a little info. on your Coach as listed in your profile:
Your GVWR = 22,000#
Your GCWR = 26,000#
So with this in mind if you are towing "anything over" 4,000# ....you are over loaded your Coach Chassis...... http://www.rvweb.com/guides/manufacturers/damon_corporation/models/2005_intruder-1097791675578

Call this company and see if they have something that will fit:

Or checkout the instructions on this one and measure your frame to see if it can be bolted on:

You have to remember putting a 10,000# hitch may not be "upgrading".

Towing capacity is only as strong as the weakest part.

Some of those parts include engine, transmission, tires, rims, axles, shocks, springs, size and strength of the frame, brakes and even steering parts. To safely tow, all these things must be considered. The difference in cost between a 5k hitch and 10k hitch is minimal. Why do you suppose your mfg only put on a 5k hitch? They could certainly pump up their advertising with more towing capacity, but they don't. Things to consider.....Dennis

I hope it works for you. I have a 36' Safari DP with a 5,000/b hitch rating. I wanted to tow my Dodge 3/4 ton Diesel pick up which weighs about 7,500 LBS. I called Monaco and the rear end/axle manufacturer and both said I couldn't upgrade to a 10,000 LB hitch as the coach wouldn't handle it and it would void the warranty. So, I tow a smaller lighter vehicle.

[my996duc1]

We had a 5k hitch on ours.
I took our RV into a hitch specialty place and they did some cutting, welding, bracing and we now have a 10k hitch. To the shop it was an easy fix/upgrade but I am not sure what all was involved.

My 5,000# receiver is bolted on w/4 large bolts now......hoping that the new one will also bolt on, see no reason to weld....

Yes, the 10k will bolt on, but you still need to weld new supports and such to make the whole assbly a 10k apparatus. Just being able to bolt on does NOT mean it is safe. Doug
