Receiver Clearance Too Short For Riser

Recommended Posts

Just bought a 2011 Holiday Rambler Augusta B+, and I want to tow my '03 Jeep Wrangler.  The Jeep base plate hitches are 10" higher than the RV receiver, so  bought a Blue Ox 10"  riser.  The shank on the riser is 8 1/2 inches from centerline of the pin hole to the vertical riser.  The distance from centerline pin hole on the RV receiver to the outside of the rear bumper is 9".  It misses by a half inch!  So, I can buy a 6" extension, which from what I've heard undermines the towing capacity, or I can have the RV tow hitch assembly removed, drill a couple of new holes closer to the bumper and reinstalled.

Any suggestions or recommendations would be appreciated.

Thanks!

Yes, multiple extension and/or riser/drop attachments are NOT recommended.  Roadmaster is adamant about that.  If possible, I believe that drilling new holes in the receiver is the better option.

 

Edit:  I was just looking at Roadmaster towbar manual for another reason and saw this ... • Do not drill a second hole in the shank of any tow bar or hitch accessory. If the hole in the shank does not align to the hole in the hitch receiver: 1) purchase a hitch a c c e s s o r y o f the appropriate length; or 2) call ROADMASTER technical support. D r i l l i n g a second hole will weaken the steel. The shank may break during towing, which will cause the towed vehicle to separate.

That was applying to the shank of the tow bar and does not address the issue of using a riser or extension in addition to the tow bar.  It also doesn't say anything about the receiver itself.

Seen like the hole location and length of shank differ among manufactures..  I have several different stinger with different heights and shank lengths.   I would not be too concerned with using a stinger with a longer shank due to the fact you don't have much tongue weight with a tow bar.

Really, I would just trim the end enough for it to fit the hole...there is enough length so as not to affect the strength behind the hole. You are only talking about a few 1/16ths of an inch, max 1/4.  Think about it, there is a lot more metal in that 2 X 2 steel shaft than what is in the pin keeping it together.  Do not drill any additional holes.

Welcome.

Bill.  That works fine for hitch.  I don't like the Blu-Ox riser,  so for mine, I had it made by a metal shop...less than $100....my jeep runs 35" tires with a 3" lift and I like my Roadmaster to be as level as possible.

Again you guys look at the hole position of the latest post by WildBill. It is 3/4 of an inch or an inch from the end...have a machine shop saw off what is necessary from the riser, it is a 20 dollar job.

Where are you talking about trimming? Where it goes into the receiver on the coach? That won't get you any where because the top receiver is hitting the coach and won't allow you to  move the hole forward to pin up. 

Carl, how does that help the OP. He already has the part.

You may want to research for a different riser, the blue ox is a good brand, but I doubt that it makes that much difference about the brand as stated earlier in another post, there is not that much weight on the device. I agree with wildbill, a 6 inch extension would not be a bad choice because tongue weight is not the issue in this case, if towing a trailer with an excessive tongue weight then I would not even consider it.

Bill, the reason that I mentioned it, was because I had the same issue when I tried the Blu-Ox riser...I had one made that gave plenty of clearance from coach and it has a extension that allowed me to use the inside pin hole.  Hard to explain, I'll send you a pic via Joe! :)

That fact THAT IT IS HITTING THE COACH COMPLETELY ESCAPED ME... I looked at the hole not the receiver against the license plate...what an idiot I am...
