Rich Experience in RV Adapters
Mumby Manufacturing Ltd. has been manufacturing 5th Wheel Hitches and accessories for twenty years.
We have a reputation for designing and manufacturing strong, reliable products
Since introducing our RV Hitch Adapter 20 years ago, we watched the RV market change and evolve,
and saw the trailers become larger and longer. Flexing in the Kingpin box can become an issue on trailers 28' or
longer when using any Kingpin to Gooseneck Ball adapter or Gooseneck extension. Our customers told us as that
they don't want to quit using their Mumby RV Adapter on their new trailer and we need to come up with a solution.
All our adapters now come with two forged tabs to provide a point of attachment for "Flex Eliminating" gussets
that are then fastened to the rear of the kingpin box. These tabs have also allowed Mumby Manufacturing to offer an
optional 6" extension that enables trucks with 5.5" truck boxes or lack of sufficient clearance between the truck cab
and ball hitch to now pull a 5th wheel RV.
The installation of our RV Adapters is fast and easy. No drilling or bolting is required, to fasten the
adapter to the RV Kingpin. A specially designed, two piece, machined block, clamps around the Kingpin.
The rest of the adapter fastens to this block and is tightened up to the Kingpin plate for a strong, safe, install that only
takes 10-15 minutes.
NOTE: On trailers longer than 28', two ½" holes have to be drilled into the back part of the kingpin box to
attach the "Flex Eliminating" gussets to.
