Not picking on you in particular but I see this mentioned a lot and I don't have first hand ownership experience with the auto transfer case in Ram 1500's specifically - but I do have extensive first hand experience with other applications of BW's TOD system and other auto-4WD on vehicles (Isuzu, Jeep, Ford) and on all of those it is programmed to engage the aux secondary axle briefly on any launch because it can't know whether it's on a slippery surface until slip occurs, so it hedges the bets by just starting off in 4wd from every stop and from any application of additional throttle at higher speeds. You can even watch the little TOD engagement indicators light up on Isuzu's dashboard to illustrate how much it's engaging the front axle - which it will do even if you're going 50mph and mash the pedal. On my Jeep which is natively front wheel drive with an auto-4wd engagement of the rear axle it does the same thing and with JSCAN software on a phone I can watch it display % engagement in real time, it always pulses the clutch when throttle is applied from a stop or while under way.
What I'm getting at here is that other applications of this auto-4wd scheme are proactive with engaging the second axle, are we sure that the Ram application is not?
On WJ's with Quadra-Drive the front axle engagement is mechanical and completely reactive so on those it really is necessary to slip first before the front axle comes in. But that's because it needs a difference in driveshaft speed to pump oil behind the clutch engage piston... that's a world of difference from electronic control.
