I'm looking to get a new dually F450, but was curious about the big difference in 5er tow ratings between it and F350. Is it just the rear springs that give it the higher tow ratings? That's what salesman told me at a dealer today. Are there really no other differences in these? Any help is appreciated. Thanks!

My Sierra Blanca in the sig pic was a great pickup for 11.5 years. I sold it a coupla years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream.

Thanks, I figured he was just trying to sell me the last '08 350 dually on the lot. I'm surprised that the frame is different! I assume beefier. I plan to get a 5er that exceeds the tow rating of the 350, so was curious about the differences.
