95 Rodeo - Low heat, hi idle

My 95 Rodeo 3.2V6 sat for just over 6 months.
After changing fluids, cleaning and getting it going again, it now runs cool and curb idles around 2000rpm.

I suspect the thermostat is stuck open but would like to know if there is anything else I should be checking on this.

TIA for any help!
