LONG TRAIN RUNNING!! 2006 XLT 5.4 Flex Fuel
I pull about 10K when vacationing, even pulled it up the Baker Grade to Cali!! Those who are around here know the Baker Grade!! Miles long, 112+ in the summer. Now I have an oversized rad, brakes, air lift, autoglide slide hitch, troyer active transmission cooler and a superchips programmer, but she handles it like a champ. I do not burn E85 when towing, it is 105 octane but I find it has less power and poorer milage than high octane gas, probably due to some egghead explanation about burn rates and compression rates of alcohol or something LOL, I use minimum 91 up to 100 octane gas (whatever is available at the time.) These trucks are animals when you treat em right!! And side note, DO NOT USE E-FANS!!! I went thru 500 bones worth of E-Fan crap and overheated, went back to my clutch fan and shroud with a DUAL core rad, that is the answer for towing heavy, not E-Fans!!!!
NOW.....keep in mind I was 10 years in the Army as a trucker baby!! Drove some pretty hairy crap! It is safe as long as you upgrade properly, brakes etc, and understand that you need to take it a little easier than a 250. Some people think that cause it can tow it, it can stop it....not the case. BRAKES BRAKES BRAKES!!! Also have massive anti sway bars, and NEVER EVER tow this kind of weight off the rear hitch, I have a 12K trailer hitch, but I would never tow over 8K unless via 5th wheel.
