Thanks again for your input.

The Sprinter has laminated sidewalls so there won't be any "hollow spots"... There is, working from the inside out, a 1/8" luan wallboard, 1.5" of foam (surrounding the aluminum frame), a 1/8" luan backer board and FILON sheeting on the extreme outside.
What you will find in your trailer is a 1/8-1/4 inch thick "TV Mount Plate" that is welded between two vertical aluminum wall studs. The studs are 1.5x1.5 square tubing. Window headers may be two square tubes welded together over large windows and only 1 tube over smaller windows.
Don't count on "feeling solid" or "not feeling hollow" as an indicator of anything "behind that thin luan wallboard.
Here's a photo of a typical aluminum frame. You can see the backer plates for the cabinets. The TV backer plate is essentially a smaller plate located in the area where the TV should be mounted.
In the photo, 1 is the FILON, 2 and 3 are luan sheeting (in light weight trailers, only one sheet is used), 4 is the "solid foam core", 5 is the window cutout, 6 is the cabinet backer plate, and a smaller one would be welded between uprights for the TV. Finally 7 is the entire frame structure. Notice that there is no "16" on center" but rather the frame is "strategically placed" where the strength is needed.
On wooden frame trailers, the construction is entirely different and the typical wood frame has "hand packed, spun fiberglass insulation" rather than laminated solid foam. On many wood frame trailers, you can feel the "hollow spaces between the wood frame members. Not so on "foam core laminated walls"....
