The down side to Dot 5 is that it takes on moisture and therefore needs to
be changed more often. Like instead of just adding like most people do,
with Dot 5 you really do need to flush and replace.

Dot 5 is real good for high temp applications, i.e. disk brakes and heavy
equipment with high temperature operating conditions, or high loads like the
big dump trucks used in quarries. For your truck I would use the Dot 3/4
very good fluid, and it will work fine.
