I come from a very tall family and my immediate family is also very tall. Everyone including my wife and two adolescent sons are more than 6 feet tall. The boys are still growing and show no signs of stopping anytime soon. We have a '96 Dodge Ram 1500 Extended Cab pickup that I drive to work and the boys and I use on weekends to haul our Yamaha dirt bikes for trail riding. Even though they take turns riding up front, one of them gets stuck in the back seat. When my wife comes along, both boys jam their knees into the backs of the front seats. My ideal solution would be to buy an '06 Dodge Ram 2500 Mega Cab. That cab is as spacious as a limo. Unfortunately, our budget isn't big enough for the big payments that would accompany a Mega Cab. My question to you is how much trouble would it be to stretch the cab of my existing truck? My truck is in great shape, and I like everything about it, except for its cramped rear seating area. If I was able to stretch the cab 1 or 2 feet, could I install the actual rear seat from the new Mega Cab? I know limo builders stretch every imaginable car and truck, so should I contact one of those companies or would a competent body shop be able to do the stretch?
Your idea doesn't sound bad on paper, but in reality it could be an expensive undertaking. You might be better off saving up for the Dodge Mega Cab. You're correct that limo conversion companies can and do stretch every imaginable vehicle, but that work is almost always done for the "trade." Many of those conversions are done with jigs on a mini assembly line. That doesn't mean there aren't companies that might be willing to do individual projects. You should check various internet search engines to find conversion companies. A good place to start is at www.limodigest.com. Limousine Digest is a monthly trade publication for the limo industry. The magazine offers an "Industry Guide" source book that you can purchase online for $8.95. Any competent body shop could theoretically stretch the cab of your Dodge, but if it were our truck we'd find an experienced conversion company. Besides lengthening the rear half of the cab and stretching the frame, custom rear doors would need to be fabricated. Since your truck has reverse-hinged rear doors, a new B-pillar would be needed to mount front-hinged rear doors.
We recently spent a week in an '06 Dodge Ram 2500 Mega Cab, and it was by far the most spacious crew cab we've ever experienced. That back seat is incredible. Our 6-foot-8-inch-tall son fit comfortably with the front seats all the way back. The whole Mega Cab rear seat assembly is wonderful. It's a split seat that reclines or folds down independently. When the seat is folded, the resulting huge cargo area is perfectly flat. There's room behind the seat for lots of gear, and there are convenient cargo loops. The bad news about the seat is that finding a wrecked Mega Cab could be very difficult, if not nearly impossible. You might be able to buy all the components to assemble a seat, but that would be expensive. It might be less expensive to have the conversion company build a similar seat.
