Anyone ever try to flat tow a GMC? I'd think you could remove the front half shafts and build a tow bar. I was thinking of using a conventional tow vehicle towd brake system to stop the thing.Might even put a vacuum pump on the GMC to help the braking. I'd be pulling it with a 2012 F350 Diesel so power won't be an issue.
Anyone ever tried this or concerns?
Any advise welcome,
Thanks,Hal

This has been discussed before. A search might turn up some answers if you are patient enough to go through all the results for "Flat Towing" (I wasn't)
Keep in mind that you will be towing a 12,000 lb vehicle. If you use a Brake Buddy or something similar, I think you would need a vacuum pump to activate the power brake booster. You would have to experiment with the settings to get it right, as they are designed for much smaller vehicles without the power brake booster in play.
You could flat tow without doing any transmission damage by pulling the axle shafts, but you would need to install a stub axle in the hubs to keep the bearing/hub/knuckle assembly together and to keep the bearings clean from dirt etc.
I suppose it id doable, but I personally would not want to go too far doing this.

My biggest concern would be that the coach can easily drag the rear of an empty f250 all over the road.
I own a 2008 crew cab SD F250 and even though it weighs 7000+ lbs empty, a 12000lb coach that decides it wants to go in another direction would easily take my truck with it. I have pulled some heavy loads with my truck, mostly without incident, but without additional weight in the box, pulling a 10000lb trailer with insufficient tongue weight can be nerve racking if you need to make an evasive maneuver.
To pull a coach i would want to have at least 2000lbs of ballast in the box to give it a better advantage since you would have zero tongue weight to help you out. Even then, i would only attempt it for a short distance, and during low traffic periods.
The consequences of your actions should something go wrong could easily cost more than a towing service fee.

I have a set of jump scales and my 'other' 1977 Royale weighs 9960 with full water tank and maybe 10 gallons of gas. The truck weighs over 9700lbs so there shouldn't be much pushing involved. The front bearings might be a concern but maybe pulling the axles and leaving the stub axle bolted on would work. It's only a 'short' trip-LV to Albuquerque,NM (580 miles). Of course, I could put it on a trailer too. Still debating.
Thanks,Hal

I'd guess you need a class A license with a trailer over 10,000 pounds.
But I'm not current by 20 years.

Got the license, my SOB is a 43,000 lb converted bus. It doesn't have an axle that weighs less than my GMC's total weight.

I think that you would want the air bags all the way up also. New transmission may cost more than a flat tow.

Thanks on that one, I remember people using that method years ago but don't know on what transmissions it will work. It would save a lot of work for sure.

Im willing to bet that the weight per tire on the front of the coach is more that the weight per tire on the rear axle of your f350. It isn't just the total weight that of the tow vehicle that counts. Now imagine what might happen should the steering of the coach decide to not follow the tow vehicle. I'm willing to bet that the coach will likely drag the arse of an F350 all over the road. That is why you need the ballast weight in the box of the pick-up.
We have all heard of the stories of those who had problems with their towd when on gravel, getting a flat tire, or just a temperamental vehicle that wouldn't track properly. Don't think it can't happen with the coach. Odds are probable that it has a better chance of happening.
I wonder if a tow bar exists that is rated for a 10000lbs+ towd? I also wonder what the local law enforcement would think of the situation? It could become a big headache to find out the hard way.
With all that said, I would probably try a flat tow of my own coach, but probably with a custom made "long bar" tow bar provided it was legal to do so through the areas I'd be traveling.

I have enjoyed lots of adventure over the years and my wife wishes i would slow down a bit but there just isn't any fun in that is there?
I never said i wouldn't try a flat tow of my coach. I just would take several precautions. I enjoy a challenge and often i'm stubborn enough to try something just because i think i can.

If you can tow it utilizing 5th wheel mount, there is less chance of tail
sway and handle it.
I'm sure additional weight towards the front of the truck can help.

Now that's a GREAT idea Jim. Not much more trouble to build a fifth wheel type bar. Have to see if the fifth wheel hitch would be up to it.

Anyone ever try to flat tow a GMC? I'd think you could remove the front half shafts and build a tow bar. I was thinking of using a conventional tow vehicle towd brake system to stop the thing.Might even put a vacuum pump on the GMC to help the braking. I'd be pulling it with a 2012 F350 Diesel so power won't be an issue.
Anyone ever tried this or concerns?
Any advise welcome,
Thanks,Hal

Randy Van Winkle and his brother towed a 23' for a short distance with a tow bar. Because of the long reach of the wheels to bumper and the tail wag of the tow vehicle, the GMC tended to want to turn right on a left and left on a right. Randy's brother had to wrestle the steering to keep it from kinking to one side. I enjoyed the story probably more than they enjoyed the towing.
