I did an extensive modification to make the rear seating suitable to long haul expeditions. Rover Accessories did the work, which was part of a bigger package so I don't have a cost breakdown. 1) Removed the bench to be replaced with two modified Cobra chairs from Exmoor Trim. 2) Cut into the wheel wells about 2 1/2 inches down and 5 inches back. 3) Fabricated custom mounts, chairs installed.
The above added leg room, lowered seating, and made total comfort for passengers for hours of travel. Seats are fully reclineable (I removed one pair of jump seats and centered the remainder so there is room to recline.) Drawback is that this reduces the 110 to a 6 passenger vehicle. Added bonus is a 'walkway' from the rear to the cubby. Added bonus: mountain bike tucks right into the slot without need to remove wheels, etc.
