We had that same tv mount inside and outside. It is manufactured by P.A.W.
We use 32 inch flat screens inside and outside. Before we took delivery from our dealer, he replaced our inside mount that was like yours with a heavier duty type once he learned that we were going to use a 32 inch flat screen. Our dealer mounted our tv on the new beefed up mount prior to us taking delivery, so I've never seen the new mount. I just know that he didn't think our mount like yours would hold that size tv on our terrible Louisiana roads. I do use a mount like you have for a 32 inch tv outside our camper and a 32 inch tv on our back deck at home without any issues.
