Thank-you all for your kind words. AAA was great updating me about ETA of tow truck on phone. The operator was courteous, professional, and thorough. We had to have a flatbed truck winch us on. Pup rode in our truck while we rode in the tow truck and didn't seem fazed. We were almost too long with our combo especially with new Ranch Hand replacement bumper. We were about 40 miles from home, so close but so far away when you have to stop every 8 miles to fill radiator. Pulled in the driveway at about 8pm after leaving campground at Klipchuck off North Cascades highway which I think is about 135 or so miles from home.
We have to have an oil change anyway and our mechanic can also do cooling systems so we will try to limp the 6 miles into town to his shop. We figure early Sunday morning to drive in both rigs and leave it in his lot for our Monday appointment. That way we won't encounter too much traffic.
I will have DH read up on the failures and will talk to dealer where we bought the truck. He did loosen the cap a bit, coasted downhill in neutral when possible but we didn't want to ruin engine. He knew enough to let engine cool before adding water and to run engine while adding water. No fun at all especially to someone like me who has panic attacks and anxiety issues. We made it and are thankful that it didn't happen on one of the Nevada canyons we traveled (South Sixmile, Hot Creek, Hunts, etc.), that AAA was prompt and that we had cell phone service when engine began losing power. Also, thankful for the locals who stopped to offer assistance and the property owner who allowed us to park in his large driveway that made it really easy for tow truck operator to load us up.
Will update about radiator and also working on TR on my blog. Thanks all.
