4x4Given, how long have you been using this app? Are there any issues you've had with it?
I've been tinkering with it for about a year. Been using Android phones for about 4 years (T-Mobile). I've just recently started to take more an interest in the truck, since we sold our previous RV (36' TT) and got the new 5th wheel, last October. It tows really nice, but you do know you're towing. It's 40' and 14,000+ lbs.
My truck has only had a single warranty repair, replaced the EGR valve at 122,000 miles, but did have all regular maintenance before I bought it at 148,000 miles. It was 2 years old and had 3,200 hrs on the clock. It was a Enterprise Car Rental car hauler. All it did was tow and run down the highway. A lot.
But it was exceptionally clean, all records, completely stock, except for a B&W Gooseneck setup and ran and drove perfectly. I was a mechanic for about 20 years and I gave it a very thorough check over. I am very well aware of the "reputation" of the 6.0L and felt that a 2007 (mfg 06/06) would be a pretty solid tow rig.
Well, flash forward 4.5 years and I've now got 180,000 miles on it and it has been pretty darn good. Degas bottle is as clean as new, no leaks, no smoke, runs great.
But... it is a 6.0L and I am now monitoring it for "signs". And right now, it has none.
And, we are about to begin the "bullet proof" process, BEFORE (hopefully) things happen.
I'm a HUGE fan of running pretty close to stock. I expect it will be kept that way, but make improvements to various items that have a history of questionable reliability.
Personally, I'm a big fan of the truck, though I would LOVE to have a 2011 or newer unit. Problem is, mine is paid for (paid $15,000) and I can't see shelling out $35,000+ for a good used 2011. Put a few grand into improving my already good truck, and have a great, paid for truck that will last me the rest of my life.
