RAM® No-Drill™ ユニバーサルマウント 大型トラック用 - ダブルスイングアーム

That double swing arm gives me so much flexibility for positioning my tablet, and the fact that it bolts right into the passenger seat rails without any drilling was a huge time-saver. The steel base feels incredibly solid, so my phone doesn't bounce around even on rough gravel roads.

Finally installed this using the passenger seat rail bolts as described, and it's rock solid even on washboard roads. The double swing arm gives me perfect screen positioning without any wobble.

Finally, a phone mount that actually stays put in my truck's cab without drilling holes. The double swing arm gives me perfect viewing angles, and attaching it to the existing seat bolts was surprisingly quick.
