Had not heard that about the 4BT. I'm more inclined to stay with newer components. If we were using this only locally you could do minimal upgrading and use it for a long time. We have done 4,000 mile trips in 3 weeks. We need modern serviceable components. Everything needs repair and servicing--even late model. Parts availability is a big issue when you are 1000 miles from home.
