1996 F-250 Overdrive Option & 5er braking

Good morning,

Question 1:

What does the overdrive option mean on a 1996 F-250 7.3 diesel?

I've tried looking it up in the Ford manual but unfortunately its clear as mud in that book (thanks Fordno).

I'm wondering when the overdrive option could be used and when it shouldn't.


Question 2:

Whats the proper way to brake when towing a 5er?

We have a 1996 F-250 7.3 diesel and a 35 foot Gulf stream 5er. The 5er has a GVWR of 10,500 lbs. 

Both the truck and 5er have air pressure at 80 lbs PSI. I understand the proper brake action depends on the circumstance, I am looking for a good general rule of thumb.

Can't speak to the use of OD on the 96. A good guess is if the engine is not lugging, OD is OK.
Braking, however is rather simple, although I have no idea why tire pressure has any impact on it. NEVER "feather" the brakes to maintain a downhill speed, rather appply the brakes with vim and vigor, reduce speed by about 10 mph, then let up and allow speed to build again, then get on brakes again, reducing speed by 10 mph rather quickly, then allow speed to build again. My Ford has the 6.0 and Torqueshift transmission, which retards soeed through gearing down the transmission with appropriate help from the brakes. No need to shift it down, let it do the work.
Your transmission will probably require downshifting.
I have found cruise control will automatically engage the transmission to retard speed.
