Just purchased 2007 Tahoe LT with 2nd row leather captains chairs. My wife very leary because we have 3 kids and one of the 3rd row seats has to be up at all times and thus takes away from cargo space but vehicle was too good of a deal to pass up. My question is can I add a jump seat to 2nd row to be able to seat 3 and if so where can I find one?
