Do it every time I hook up the 5er!
never been an issue for me, 1st is usually not too low for stop & go traffic, not that hard to go between 1st and 2nd anyway. We usually get stuck in some S&G traffic every trip to the Oregon coast through the small coastal towns. Watch your revs, don't lug the engine and you should be fine.
Use the Exhaust brake and gears on the down hill side of hills, you really should not need to use your service brakes except, if traffic slows suddenly or the grade is steep.
One other thing, with a diesel, you don't need to slip the clutch, don't "dump it", but you don't need to rev before releasing quickly. Drive the truck through town a while to get use to the feeling.
