one year with a 40' fifth wheel and dually
Its been just a little over a year that I have had my current setup which includes a 40' Cyclone toy hauler and a 2001 f350 dually. I figured I would share my observations given how many questions are...

No tunes? I use the Edge CS on level 2. One time a few weeks ago I drove to the coast over the Oregon coastal range mountains in stock tune and the truck was absolutely pathetic. On the climbs we were lucky to maintain 35mph. With the weight that you're towing do you have the same performance issues?
No tunes. I have an old Edge w/Attitude tuner but only use it for gauges. She has a few goodies for reliability and towing, but no real HP mods.
Its pretty slow going over passes and really steep grades. It will drop down to about 35-40mph. I have to really keep an eye on the EGTs at all times. Some grades I can only give her about 1/2 throttle to keep EGTs under 1250 degrees.
Get her out in the flats and it yanks my trailer.
One of the many plans for the truck is to regear to 4.13s.
