Well - all went well. No mishaps except for my brother moving my CRD while I was there and leaving the keys turned forward all night.....dead battery in morning. Threw quick charge on it and all was well.
Background info. I hauled a coleman popup weighing about 3000lbs+ and approx 25ft in length. I started from Salt Lake and up I80, across Wyoming and then back down into Colorado. About 420 miles each way. Elec surge brakes.
Details:
* Looks like I got just shy of 20 mpg on 1st tank and that was up I80 for those of you familar with road!!! Didn't keep track after that.
* I could have ran just about any speed I wanted except that at about 72+, I got quite a bit of swaying of trailer which really pushed me around. Didn't matter how I loaded the darn trailer. Next investment=sway bar!
* Checked oil at fill ups and didn't use a drop.
* I did add 4 oz of Power Service with each tank after the first and I have to say I could notice a bit of difference in noise. (Funny note, I was in Flying J truckstop trying to figure out which Power Service to buy when I watched 4 truck drivers come in and buy the product. Made decision pretty easy and if the pro's are using it, must be something to it)
Fun Note: Had a chance to throw it in 4 wheel drive(without trailer) and bomb around the area. What a blast! Went up and down a few washes..pretty steep too and absolutely no problem. Also was running about 45 or so around sandy/gravel corner and the ESP kicked on......pretty cool but a little boring

. I was ready to power slide around corner but no need...just pulled me around the corner. Excuse my gee whiz gushing here, never had vehicle with this option.......
Thanks for all the advice and take care.....
