Big Puppy,
We have a '99 36 ft Kountry Star by Newmar and love it. We looked for over a year before we decided to buy. We've taken it out west twice, and leave again in 18 days. We also pull up to the Smokies.
The Kountry Star has two slides (living area and in bed room) and weighs about 14k when we're loaded for a long trip.
So far the only problem I've had has been with the fridge. A dirt dobber built a clay nest in the burner tube. The folks at Newmar told me what to look for. End of problem.
Go to the Newmar board, I think it's newmar.com. They have something called the Kountry Klub. Lots of info there. They also have a classified section. Bet there are some good deals there. I'm getting ready to advertise ours for sale. Nothing wrong with ours, we have horses and my wife would rather have a horse trailer with living quarters.
About towing: I had a tough time pulling before I modified my truck. The first trip we went to Tennessee. At one point on I-75 I was making maybe 45 mph. I had no guages on my truck and everything was stock. Look at my signature and you'll see what changes I've made. Since the modification no problems pulling at all. Best modifications are the TST plate, Pro-Loc torque converter, and BD exhaust brake. Now I can take the same stretch of road where I was used to do 45 mph and hold 70 without a second thought, egts at 700 and trannie temp (in the pan) at maybe 140 degrees.
Hope this helps.
