Hey mudmaker, it's been awhile.
I have the 05 F350, and I love it. Like they said about the maintenance, I usually go the the dealership, I know my service writer. I use the syn. oil and do change the oil regularly.
What kind of towing are you going to do? I recently bought a Mag Hytec tranny pan, it holds an extra 8 quarts of tranny fluid. Also the 4 guage pillar set-up. It's just a peace of mind.
Plus I installed a SS steel MBRP 4" turbo back, that helps alot. I don't have any complaints or problems to date. (Great, now with that stated, watch me start having problems. Damn Murphy's Law!
LOL) I hope it works out for you, they're nice rigs. BTW I did get the pictures of your trailer mods out of the towing section. Nice!
Do the 04 F450 have the coils up front? I know the 05 do.
You'll love the power and the ride.
