dual 6 volt possible??

Hi, i have searched for days and cannot find any specific information for converting to dual 6 volt batteries and supporting the weight

2011 fourwinds majestic 28a on a E-450 chassis with the v10

what i am trying to find out is if the stock battery holder can support the weight of dual 6v batteries about 120lbs total, it has a slide out tray with room for 1 31 group 12v battery. It has two steel plates that are bolted to the bottom of the motorhome that create the sides that the sliding rail bolt to, i cannont find what the plates are bolted to to (some say its bolted to just some sheet aluminum) but its all covered with sheet aluminum and i cant see from the top because the heater is there. I really dont want to remove the heater to find out.
my plan is to just weld a steel plate across the bottom of the two sides and make a hold down for the batteries and get rid of the slide part.

Would this work or am i overloading the hanger? does anyone have experience with this on a majestic 28a?

Thanks for any help!

I would submit a Thor Customer Care request using the VIN of your coach and ask if they can send you the engineering drawings of the battery compartment or at least explain how it is constructed. If you explain that you are trying to move from 12V to dial 6 V they may send you the drawings.

If could be a crap shot, however, given the age of your coach as to whether or not Thor has or will send the drawings.

You can submit the request here
