   Don't you recharge it from the truck system ?

   You need to get a "Leisure Battery"  this is a secondary battery used in   
   campers/caravans to supply power.  Mine is rated 185 Ah and lasts about   
   12 hours from full charge, but not at 25 amps !  My average draw is   
   only about half that.  Though the fridge takes a constant 7 amps.   
   You can get much bigger ones.  I've seen 330 Ah for sale.
