How Wide is a Dually? Always Need Dually Jacks?

There might be small variations, but there is no way you can squeeze 8 feet wide fenders between 7 feet jacks.
Even with jack extenders I have less than 1" clearance per side.

There not exactly the same but close..In buying my camper we took it off a late model 90's Dodge DRW which was very close,then we put it on my '94 F-350 DRW and the guy said,that was easy.(Laughing)There was slightly more room on my ford squeezing between the jacks then his Dodge.

Then came the close calls his wife and he had getting it between the jacks.

So yes,they are necessary for a dually.

If I measured right, my duly finders, from edge to edge is 8 feet. (2014 Chevy Silverado)

I can't imagine any would be less than eight feet. Then you have to keep in mind some people install oversize tires and/or wheels, making it wider. Usually the wider tires require wheel spacers making the rear even wider.

This will also depend on the camper and how the front jacks are mounted to it. My Bigfoot had the swing-out jack mounts - but when swung out they still would not allow my Ram dually fenders to pass between them. I had to build extenders out of 4" channel to make them work.

Thanks all. My jacks are 90 inches apart and have no swing outs, so that's that.

The camper is 3,000lbs, and I have it for sale. I figure somebody that comes by will have a dually. Now I know what that means. ( I could deliver it after purchase and he could sort out the jacks later at his place on his own time)

My 2003 Chev 2500HD gasser is about 75 inches wide and can just take the weight. Its CWR is 2770 lbs so I steal some front cab weight allowance to make it up to the 3,000. Back tires are right on their max. I am telling folks no 1/2 tons or 3/4 ton Diesels, but without the swing-outs, that leaves no duallies either! Oh well, we'll manage :)

1 inch clearance either side--yipes! Must have nerves of steel.

Hi BFL13,

Nope they are not all the same width.

You could always buy and install the swing out brackets yourself. The 200 bucks or so might make it easier to find a buyer.

Don't tell the weight Police, but I hauled my 4200 lb TC for about 185,000 from 2004 till 2016 on my 1996 Dodge 2500 ext cab 2WD. Air bags with no overloads, sway bar, and 19.5 tires and wheels. Never had a problem.

I would not haul it on stock suspension, and stock tires were borderline. I upgraded to a 2004 Dodge 3500 DRW 4x4 for the creature comforts (softer ride) and wanted a change after 14 years.

Both of the TCs in this photo weigh 4200 lbs.



I would advise a potential buyer they should have a 3500 (not necessarily a dually) or a 2500 with upgraded suspension and tires. When you look close at the 2500 rigs most are way overloaded (per door decal), although few will admit it.

We also hauled out bigfoot 10.6 on a 1994 Dodge Ram 2500 with airbags as well no issues. At that year the 2500 was built like a one ton. Dana 80 rear axle! We were running around 4k as well.

In general I have never placed limits on buyers vehicles as a term for sale. I simply tell them to do their homework. I am not engineering solutions or offering my unprofessional opinion.
