tst-507 system
Nobody has added to this post in awhile so I hope it is still being read because I have a question. I plan to purchase one of these systems four valves systems soon. I see that e-trailer has several models of the four valve system. My question is when the tire monitors are installed can you adjust tire pressure up or down without removing the sensor? Does 'flow thru' mean that you can. In reading some of the descriptions on e-trailer web site the TST-507-XX-X designations are a little confusing as to this capability.
Thanks
