When I assembled and installed my 2.1 into my beast in 1997, I made it a primary goal to circumvent any and all possible leaks by checking the hose connections. Installed a new radiator, water pump (a matter of course with a new engine) and a new pressure cap (in fact I recently replaced the pressure cap on the principle that it was 5 years old and due - it's good cheep insurance).

I continually run with the needle just to the left of the LED. When getting off the highway or after a good run up a grade like the Grapevine outside LA I usually don't have the temps go up when I hit the rest stop at the top of the 'Vine. Going up the grade I see the needle creep up, but it's normal. When traveling around the USA in 99 fully loaded with the trailer I never once had an overheating problem.

With that said, I do agree with Jeff & George that in "some" cases constant overheating and the quick fix of a cooler thermostat can mask the problem. In addition, I only recommend the use of an 80c thermostat in Westy models usually because of the weight they have to pull. With 7 passenger and pickup models all things being in good shape, the 85c thermostat is an excellent choice and there shouldn't be any reason to run the 80c thermostat.

On Diesels however, I strongly recommend running the standard thermostat temp range it originally came with because diesels run more efficient at normal operating temps. Never run a colder thermostat in a diesel (my experience with a 81 Diesel Rabbit PU will attest to that.
