I use the 138, 14, 395 with bike, car and rv although it is a bit longer than 395 (on my Reno - Redlands 4 times a year trips). I also have a couple routes to get around the Lancaster/Palmdale stop go traffic. Recent work (still in progress) has upgraded the lanes and I find the couple miles added to the ride are more than made up by the reduced stress of driving through Adelanto and the sections by Kramers junction. It seems driver common sense and courtesy disappear between Ridgecrest and Adelanto.
