Thanks everyone for the advice.
I thought it was me but I tried several times to get the Delorme to work and never had much luck. I have plenty of memmory on my lap top.
What I couldn't understand is the trailer life would work great. The Delorme with or without the GPS didn't work.
I contacted Delorme and come to find out I have a bad CD, they sent a new one (complete set minus the GPS unit) over night. I put the disc in and bingo it works great. I should mention Delorme bent over backward to make sure I was pleased with their service.
By the way for the nice people that gave me advice on our trip out west (5000 miles plus) thank you. I told them it was my first time pulling that big rig through the mountains and I was scared to death, I almost backed out. Well we traveled all through Yellowstone and several other mountain ranges, that 5er pulled like a dream. The thing I liked best about our Chevy 2500 diesel was going down steep grades I could put that Alison tranny in trailer mode and it would walk me right down without using the brakes very often. A couple friends we traveled with had to pull over several times and let their brakes cool down. They drove a Dodge diesel.
Thanks again,
Bill & Rita
