clutch slipping?

[hans mowman]

Just got my new chip today and all I can say is wow! Unfortunately about 5 minutes into my charter voyage I really started getting onit and immediately noticed my rpms shooting up. Happens in high gears, low rpm. Doesn't seem to happen in lower gears.so three questions...

This is clutch slippage right? I'm impressed but I don't think I'm spinning tires at cruising speed.

If so, how long do I have before failure? Im actually going on vacation Saturday, 600 miles round trip. Never been an issue before, and I haul a 10k bobcat, as recent as last week. Never noticed a hint of a problem. How quick a process is it from the first signs?

If im looking at replacement, any recommendations on an upgrade without getting too pricey?

6sp with 130k. I got the truck with 60k and haven't put one in, so im assuming its original.
