Both my 2003 and my 2014 I drive in 4A 99% of the time. I have no reason to drive in 2H to save gas which is the reason people normally give to do that. I do put it in 2H sometimes just for the heck of it. I cannot tell any difference in normal driving and I never have heard any noises like you mention. Same with the 1999 I previously owned. In special situations I also use 4H and 4L. Thats 400,000 miles of experience in 3 Expys.
Dealer telling you not to use 4A on dry pavement ... either there is a misunderstanding or he is way off wrong and does not know what he's talking about.
My understanding is that the front is "engaged" (as you phrase it) once ... When you turn dial to 4A and stays that way. Power is applied as required by the Transfer Case in 1% increments from then on, the 4WD doesn't connect and disconnect.
