I suggest you go to the Jayco owners forum on iRV2. Lots of Seneca owners there. We looked hard at these (I loved them). GVW is 28,000#. GCVW is 33,000#. Tow rating is 10,000#. As long as you underload the Seneca you can easily tow up to a big SUV or pickup. How well, I can't answer.
But if you are from those few states which require a Class B or A license to operate a GVW>26,000#, check that out.
