I would agree with john here

it idle drops down to 180.

     180 degrees at idle in almost any weather
     175 to 180 degrees on the highway when air temp is below about60.
     185 to 190 degrees on the highway when air temp is above about80.
     190 to 210+ degrees when pulling an 18 foot travel trailer.

>These temperatures are taken at the side of the thermostat housing.


But my thoughts would add

>My questions are, is the location as accurate as the thermostat 
housing?

The side and top of the housing( like such chevys and fords) are within 
milli-degree's of each other.

>is it getting too hot on the highway, and why? I need to get this taken 
care of quickly before going on a four hour trip to the Nationals.

It almost sounds like the clutch fan is not disenguagine on the highway. 
remember ram air from highway speeds is much more than the fan will draw 
in.

 I would think about o'haulin the cooling system. Go to napa and get a 
180' thermostat 3 gal coolant and rad cap. I was on the way to the 
Deschutes River for a weekend of camping and fun, and the scout gave me 
nothing but trouble with 3/4 on the guage. I finally pulled of at The 
Dalles and sent my lady to the auto store got the t-stat and road side 
put one in. I was reluctant to think it was the t-stat as to I just put 
one in months ago, but it was a cheap oportunity. And @#$% if it didnt 
fix the problem. Never got 1/3 on the guage all weekend.
