We just returned last week from a 29 night trip up to Wisconsin, Michigan, Ohio and Indiana. All told, we put 4095 miles on the truck; probably well over 3000 pulling the Stone Ridge. The trailer performed perfectly! Zero problems. We've owned the unit for about 18 months and have put at least 8 to 10 thousand miles on it and have spent close to 150 nights in it. The only issue we've had was a defective sending unit on the power door lock which KZ replaced when we were at the rally in Shipshewana. Incidentally, they came to the campground and changed it out! This is our 4th 5th wheel camper in the last 9 years (the 1st KZ), and we couldn't be happier with it. I'm looking forward to many more trouble free nights and miles on this unit. I'm not expecting the unit to be trouble free it's whole life, but it sure has been a pleasant experience so far. The trip to the KZ factory was very informative and I got to see 2 of the same model unit that we have in different stages of assembly. I again want to thank the folks at KZ for the hospitality they showed to all of us at the rally. I'm looking forward to a rally next year (under preliminary planning now) and hope we'll have a bigger turnout. Just because you yankees don't camp in the winter, don't be a stranger on the forum . I'll try not to rub it in that we southerners will continue to camp all year long!
