I was lucky enough to buy a great 2017 GSA/DMC rig from a fellow inmate (photos below). I have a couple of questions some of you more experienced folks may be able to help with. In no particular order: 1. I am looking for tire pressure recommendations (to use as a starting point) for the rig. Usual load is 1 200 lb person and 100 lbs of gear. - pusher tire is Michelin XZX all-weather radial size 165/SR 15 - sidecar tire is Michelin XZX all-weather radial size 165/SR 15 - front tire is Michelin Commander II 160/70B17 (has DMC widened front end) 2. Is there any way to turn off the TPMS (aka RDC) warnings? 3. Does anyone know what the mysterious black box shown in photos 3 & 4 is (2 views of the same box). This is under the front seat. The rig has after market Touratech ESA suspension, front and rear - could it be part of that system? Thanks in advance for your help.
