We got home safely about 1:30 p.m. today. The last four miles from I-5 Exit 270 to Birch Bay this afternoon I was holding my breath. I did not utter anything out loud so as not to jinx us! But we celebrated on our deck over margaritas...FINALLY, a trip to and from Lake Powell with (A) no tow vehicle breakdown, and (2) no trailer issues, no overheated hubs, no wheels flying off, no flat tires, no nothing! This may be "situation normal" for everyone else, but it is a BIG deal to us!
We traveled a total of 2,466.5 miles, and the Silverado 3500 Duramax turned in a consistent 10 - 11 mpg, low of 9.8 (Blue Mountains in Oregon) and high of 11.5 (most of the flat parts of Utah and Idaho) running at about 60 - 65 mph. I don't tow faster than that, this speed seems comfortable and safe.
I checked the hub temps regularly both ways, always under 100 degrees F. I checked the Bearing Buddies only on arriving at Lake Powell on the trip down, but every morning on the way back, and was I surprised at how much grease they took each morning so the plates would flex. I now have a couple of extra tubes of Lucas Red 'n Tacky No. 2 in the truck, and will be careful to check the Bearing Buddies every day from here on out.
The big deal for this trip was no exitement, zero, nada, nothing, which is exactly how we like it!
