Articulation is good (tilt, swivel, extend). All points of motion can be tightened so as to prevent unexpected motion while travelling in RV. Mine came with two wall mounts. I presume you may want to move TV from one area of RV to outside. We mounted a small 22" TV, but the unit can withstand a 42" TV...the issue is will the walls in your RV have ample support for such a large TV. (I chose to stay small)
Perfect for my small monitor.
-Extends out a great distance if needed and tilts in every way possible -Quality firm hold -HDMI cable and cable management on the bar -So many possibilities
Great construction, easy motion when loaded with tv, feels solid with 65" plasma installed on it, great cable management, I trust my tv on this one!
