2008 F350 SRW switch to DRW

[Sayonara]

Am i crazy to ask.....?? I have a 2008 F350 CC PSD SB SRW. I use the truck only for towing our 35' TT and am looking to upgrade to a 5th wheel. Having DRW would allow for a higher pin weight and better handleing. we love our truck and i though if it was possible it might be less costly to swap out the rear SRW axle for a DRW and some fenders then trade it in for the F450 i know id end up getting.....

Thoughts?

perhaps getting a wheel adapter conversion and adding fenders u just cant off road it or u might break something.

Im completely clueless about this so im gonna ask....Are you serious. Is this available? is that essentially what the DRW axle would be and would it improve my cargo capacity? Hmmmmm....

Dual rear wheels don't increase your pin weight capacity that much, believe it or not. It might increase it by 500 lbs or so. The only thing that significantly increases capacities is going from an F350 to an F450/550. Let me find the charts and get back to you.

Oops...maybe I spoke too soon. I know these are just 2006 figures, but you'll get an idea from these charts. Go here http://www.trailerlife.com/towrating...ngs_p20_33.pdf.

The dual rear wheel(DRW)trucks use the Dana80 axle,most are 4.10 ratio,with a 4"axle tube.To go from a SRW to DRW you'll need new ubolts and top plates as well as the outer bed wheel fender extensions..best bet is to find a wrecked DRW truck and buy a rear frame clip so you get all the brackets,springs,hangers,driveshaft setup and such for the swop.If I were you,I'd avoid the F450,the axle gear ratio is 4.88 and will kill your mileage,as well as it runs the (19.5") bigger tires that are more expensive.I'd avoid the dual wheel adapters like the plague,a dual wheel axle puts the wheel hub farther out between the wheels,supporting the load;the conversion kits don't and put too much stress on the axle bearings in terms of outhung load.I have a F350 DRW PSD and it'l tow anything you need..and does 15Klbs with me frequently.
