Transmission temperature
I have a 1998 f53 chassis title as a 99 Winnebago with a V10 and my question is with an OBD2 ScanGauge where does it read the temperature before or after the transmission cooler if I remember correctl...

Since the F-53 has a GVWR over 8500lbs (and if not originally sold in California) it was exempt from the otherwise fleetwide OBDII requirements of 1996. It will have the OBDII connection port and PCM but it is loaded with OBDI calibration.
Even with the OBDI calibration a plug-in device or dongle in the OBDII port should report the trans temp on a V-10 4R100 combo.
The above information does not appear to be very well known and has sparked many "debates" on various forums, but it is the reality of these early over 8500lb vehicles.
Here is a good thread with lots of info about the situation and what you may expect between the two calibrations both using the OBDII port and hardware. https://www.ford-trucks.com/forums/518596-wondering-why-your-mil-doesnt-come-on.html#post3889931
