Towing behind a fifth wheel

[DBISS7]

Just bought a new 310 - Has anyone after market upgraded the 2" hitch (behind the fifth wheel) for additional towing - I have a 12' trailer that i want to haul a Kawasaki Mule - on the CAT scales it weighs about 3500#. The hitch behind the 5th is rated for 3000# -

Thinking i could weld some extra supports under the frame - Anyone messed with this??

thanks

Congrats on your new 310.
I would be concerned that it would void any warranty you have on the unit if it is "messed" with.
Proceed with caution.
