Blacksnapon:Thank you for your input. Sounds like I'm riding around on a one ton suspension for nothing. On the plus side: It's a really nice truck and low mileage; runs as smooth as my wife's' 2011 Expedition and has the same 5.4engine. I'm confident it will handle my 6200 lb. boat somewhat...

Bought an '08 350 because I thought I was getting a one ton rear differential/axle and the appropriate front diff. also. Some on-line searching reveals that I likely have a Dana 60 diff. which is the same one used in a 250. A Dana 80 is optional and I think is used only with dual rear wheels...

Hi. This is Dave. Have a newly purchased 2008 F350 XLT 5.4 gas 5 speed automatic 3.73 gearing. Happy with it so far and traded my half ton because I purchased a larger boat. Have some questions that I will post in the regular forum. Thanks.
