Diff lock

You may be describing what you're asking incorrectly. Are you asking about an "inter-axle" lock (often refered to as a diff lock in ads), or a differential lock? Inter-axle locks the driveshafts together, differential locks the axles of opposing (left to right) wheels together.

I do not have a diff lock on my 2014 volvo so I don' t know of the advantage. I came singled from the factory so can I add a diff lock very easy?

If the truck has tandem axles, you will generally have some sort of inter axle lock. Differential lock is a different thing altogether.

 

The short answer is, if you are going to be operating in non paved and questionable traction environments, diff lock is very desirable.

I have had my share of sliding on wet grass and bogging town in relatively little mud. We visit several parks that have large hardy lawns for pads. Very pretty till a week of rain sets in and you realize that the soil under the lawn is an absorbent clay that is turning into a mud bog. Does anyone have a ball park estimate of what the cost of adding a locking differential to a Volvo 730/780 might be?

I am seeing/budgeting about $2k for a used rear end, right side axle with the longer splines, and fluids. This thread discusses it a bit more:
