Thanks DaveBen! What are your thoughts on my new (ordered and due in) Ford F-250 vs my existing 2001 F-350 for pulling and handling my 2007 12k lbs and 40 ft long Designer fifthwheel?? The rating on both the new F-250 & F-350 is 16,000lbs for towing/pulling,BUT will my new F-250 be able to handle the 2,780 lbs hitch weight? The new F-250 has better suspension,trailer sway control,and more torque& HP---My old 2001 F-350 (11,500 gvwr package) handles it ok. Maybe I should order a new F-350 or keep my old 2001 F-350----Not sure any help appreciated! Thanks!
