4th Door Conversion

milehighgmc · July 28, 2004

Ok, boys tell me what you think.

I have a 2000 GMC EXT cab but I only have the 3rd door. In 2000 they only offered the 4th door at the end of the production year and I of coarse bought mine at the begining of the year.

Does anybody know if my truck can have the 4th door added. I assume it might be a bit pricey but I have way to many aftermarket stuff on the truck for me to want to buy a newer one. Plus its paid for.

Any thoughts?

By the way, I just joined the forum so be easy on a newbie.

Call me crazy but I think this would be a major structural overhaul, but not impossible. I do think it would be cost-prohibitive to do, but not if you're willing to fess up the dough. If you can find a 4th door at a junkyard, along with all the hinges, latches, etc, a good custom shop could cut the driver's side up and set you up, but I'd hate to think what it would cost.

I am afraid of what it might cost as well but I would love to convert it to a 4th door. Its probably going to cost too much but I was wondering if anybody else had done anything like this.

It would be cheaper to buy a 4-door cab and swap it for your existing cab. Then everything would be aligned right too.

You are thinking outside of the box! I would have never thought of this but it is an excellent idea - and would probably be a lot cheaper.

Cab with rear doors runs about $1000+, painted to match your truck another $1K, interior pieces you will have to swap..around $200 or more. PLus all your work involved.

Having your cab modified to mount a 4th door would cost in the thousands by the time paint is done too.

I would prefer the first method, but I don't think I would spend the money just to get another door in the back.

Swapping out cabs would be they way to go IMO.

swapping out trucks would be the way to go. If you sold your truck privately you could get an 2002 for what it would cost to add the door and you would have less miles.

I saw on the History Channel a place in Minnesota or Michigan I believe, that specializes in adding extended cab, crew cabs or extra doors to pickups. They took a crew cab f**d and added 4 full size doors plus and extended cab with a door that opens on it. They did this on any make model and year . They showed a 71 chevy that they put on extended cab on. They had to stretch the frame and made there own doors but it looked factory. The average price was between 10 to 15K.

Hah I think I saw the same truck on TRUCKS! Had all knids of "tailgater" kinda stuff. Truck looked super clean too.

The show on the History Channel was a special episode of "Modern Marvels" where they showcased trucks. That stretched F350 was pretty bitchin. It was big money but worth it for the purpose for which it was built, to haul a very large family plus tow a 5th wheel.

The truck that was on the show "Trucks!" was a demo rig built by BullyDog to showcase the 'Ultimate Tailgater'. That was pretty cool too.

Back to the topic, I think the option of swapping cabs is the best way to go. Be sure you don't pick one that's up into the '03-'04 range unless you plan to add the latest style front clip too. I'm not sure the fenders would line up. Just my $0.02.

Bayer Built in Elrosa, MN also does this. They were taking extended cab truck and turning them into crewcabs long before they existed in some models. When we go to the track to race there is a white dodge dually that has 6 full sized doors. Almost like a limo conversion....

IMHO I would just trade it for a new version of what you have with four doors. A lot cheaper route!

Back in the Cold War era we had these on the flightline for B-52 alert crews. It was the only way to fit a full flight crew into one vehicle without leaving someone in the bed of a 1-ton Chevy screaming down a snow covered North Dakota fligthline when the horn went off. Just monsters of trucks! Had to be 26 feet long.
