hello all,
has anyone used a modern spare tire carrier from a pickup or SUV? The kind that goes under the bed and uses a crank to lower the tire. I guess you would have to relocate the dump or us a macerator. I would just free up the back for a grill, storage box or bike carrier .
just wondering

With many coaches outfitted with "tail dragging wheels" under the rear end, I wonder if clearances would be a major problem?
My previous coach, P.O. had put the spare under the converted bed in the rear, with an access door above the bumper and below the window. Clean look, but destroyed a large amount of space.

I've ruminated over this a bit and have a couple thoughts. Not saying they are good thoughts...just thoughts with little investigation behind them. Obviously, I haven't done this yet either.
There is an issue with tail dragging. Hanging a 12" thick wheel and tire combo mounted under the floor isn't going to help even if it's mounted as far forward as possible.
We do have that empty area behind the engine. I THINK it would be possible to cut into the floor behind the drivers seat and mount the disappearing spare using the pickup mounting bracket. It would probably get pretty nasty and oily from engine drippings, stuff thrown from tires. You'd need to put a hump under whatever furniture is there so the wheel offset could stick up and the tire NOT HANG DOWN BELOW THE FRAME.
I've also thought about trying to make some kind of 'space saver' spare so I could limp to the nearest WalMart (I have WalMart tires because there is one on every corner.) If I could find or make a non-offset tire and even a smaller tire with enough load rating, it would be possible I'd think. A different offset would work on the front for a SHORT distance so one would have to swap tires around depending on where the flat was. Same with a smaller diameter spare, I'd want it on the back.
Of course, one could just go with quad bags and not carry a spare at all. Some don't.

Kerry,
Scroll down to the bottom of the link where there's a photo of a '26 GMC frame, where would you put the spare?
http://www.bestclassa.com/history/GMC_Production_Marketing.html
The vertical section of the frame is 6" you so would have a hell of a hump in the floor.

When you actually need the spare, the coach will be down on the flat making it more difficult and dangerous to get the spare out. Plus you should never get under there without blocked support especially under the air suspension.

I would never have thought there was room for a spare under there, but Bert Curtis is in the process of working up an under frame spare on their coach. He's making his own wheel and will be using a narrower tire for the spare.

If you want to reclaim the room on the back, you could get a front mount spare carrier. Not sure how that would affect cooling.

Kerry,
I know some don't carry a spare as they let Coach-Net bring a spare to them, but can quadrabag owners safely drive with just the one tire? The remaining tire would be seriously overloaded. Maybe if a tire blew within sight of a Wal-Mart that would be okay, but other than that it seems like a fairly risk alternative. What's the scoop?

Not a gmc, but
I drove a Beford truck with 20 passengers in the back in the Indian Thar dessert
After 3 flats drove a substantial distance with single wheels to reach the nearest town with workshops ( lucky we did not puncture again 3 wheels would have been difficult))
Seems to me that tires can take a lot more than what is written on them.
If you drive in populated areas you would probably be allright

I just know of a couple folks who do that. I think Nick ? from Florida? doesn't carry a spare. He has a diamond plate tool box mounted on his bumper.

Yeah, that was the same thing I was thinking. A steel wheel that is modified for our bolt pattern but without the offset would make a spare that is in the 6=7" range. Again, if I went to a smaller lighter capacity tire, I'd only be easing down the road to the next WalMart, not continuing down the internet at 70mph. If the flat was on the front, I'd pull a tire from the rear and put the small spare on the back with the normal tire on the front. Even a bit of load carrying capacity on the little spare would make it a lot better than nothing. And I don't yet have the quad bag setup.
Yeah, a bump under the couch might be necessary but I've got that option with my configuration (front twins of my own making)

Todd,
I think the tire and the mechanism to lower it would extend way below the frame and you'd wind up tearing it off the first gas
station you pulled out of.

Use a spare with less offset and mount a small wheel (or 2) through the lug bolt holes of the spare.
