Too much caster?

Just had an alignment to Thuren specs due to the truck pulling right. They didn't adjust the caster, just the toe.Is this too much caster? The cross caster is in spec. The bolts for the caster adjustment are about at 6 o'clock the passenger side facing the front a little and the driver's side rearward. The steering does feel a little heavier now than it did before.

I run mine at 4. Ran it at 3 for awhile but went back to 4. Steering feels balanced. Marks on Castor bolts should be about the same.
I'd take it back and ask them to complete the alingment the started. Toe is only part of the alingment.
 
FWIW,
I just had my new 3500 aligned at 500 miles by the dealer, mainly because the steering wheel angle was at 11 o'clock when going straight on any cross sloped road. Couldn't stand that...
Alignment turned out fine but
my left front caster is (-5.3).
Asked my friend/manager at trusted local tire shop to look at results and they said not to worry, won't cause any tire or suspension issues.

Agreed.

I only completed the Thuren specs about 1000 miles ago, but caster's at 4 and feels great.
