Sorry...another tow vehicle capacity thread

............I know I am not alone out there as far as towing more 5ver than the truck is rated for...I think the most popular combo I see on the road is SRW truck with 5ver behind. And even if some of those are 350s/3500s...the GVWR capacity of those trucks isn't different from the 250s/2500s.........

Just because others do it does not make it right. I think you will find a lot of those SRW trucks are 1-tons.
And your statement about GVWR is totally false - the 1-ton SRWs usually have AT LEAST 700# more payload capacity than the 3/4 tons.
If you mean GCWR, not GVWR then you are correct, given the same axle ratio.

Your problem is you have a heavy truck, which limits your carrying capacity. There are 3/4 ton trucks out there with a lot higher payload rating. Diesel, Crew cab and 4WD, plus all the "extras" take their toll.

I echo the sentiments about denial of warranty and personal liability if you were ever in an accident. Although rare, I have personally been aware of both situations while working for one of the OEMs.
Not sure if it would make a difference but if you had the rear of the truck PROFESSIONALLY converted and documented to F-350 components it MAY be a mitigating factor.
Reality is you may well still be over the GVWR of an SRW F-350!!

Don't add the extra tank. I know filling up every couple of hundred miles is a pain but it would not help your case if ever you had a problem.

BTDT, my 1st fiver put me 400# over GVWR when loaded, which is why I now have a 9600# GVWR 27 footer, with 400# of payload to spare.
