Don: based upon recent research, the 180 stat is the best one as noted in a recent posting by me. I got the new thermostats and on a cold day started to work on replacing my 160 stats. The job isn't hard, draining coolant and saving it for reuse, but then, at least in my 93 coach, it is made difficult due to limited access to the thermostat housings. They are buried behind air cleaners, exhaust pipes going to the turbo, and the left one has part of it under a bracket holding the ECU. I decided to wait for a warmer day when my thick clothing wouldn't interfere with mobility. My coach also has the exhaust pipe from the turbo to the muffler getting in the way a bit. It may be possible to do the job without removing the pipes but it will take patience and contortions. So, my advice is to make a thorough check of how you will access the bolts holding the covers (4-6 each cover) and get access to the 14 (I believe) hose clamps that will need to be removed and put back. Also, depending on when all those hose were last moved you will need to have a plan for loosening them or cutting them. It really is a straightforward job, it's just the access issue.
