My thermostat is 98-101 around town, the old one was 106-108 just like yours. I run my car a lot at full throttle so I was hoping the extra cooling might improve performance slightly and engine seal life. BTW what I mean a lot at full throttle is full throttle for 100's of miles at a time. When you tow you are probably running full throttle about 80-90% of the time while driving.
