TV Mount Installation for Seismic

[job]

I just purchased a Seismic 395 and I am looking for some information to install TV mounts in the garage and bedroom. I have searched the internet and this forum and I haven't found the information I need yet so here are my questions:

1. Is there a metal plate behind the walls in the mounting plate area? I have seen some information that suggests this but I am not certain if it's true for a Seismic. This would suggest I need self-tapping screws for the mounts.
2. The depth of the walls. I want to make sure that I don't drill too far into the wall. I suspect the depth is around 2 inches but I would like to hear from those who know for sure.
3. Any other considerations / issues you may have experienced during your installations.

Thanks!

I have '23 Seismic 359, and have mounted TV's in the garage, bedroom and outside locations. I know the TV backer in the living room is 3/4" plywood in mine because I can see it where the hole is cut for the HDMI cable. You can remove the plastic grommet in the hole and see it for yourself. In fact, I switched the LR to a 50" and changed to a beefier mount just today. As for the garage and bedroom, they don't feel as robust to me, put two round trips of over 1000 miles, and they haven't moved with 1" coarse thread wood screws (as many as the mount has holes for). That includes the 50" with a lesser mount prior to today. I also secure them with nylon straps with plastic buckles when traveling. I did not encounter any metal plates. I hope that helps.

We have a 2023 Seismic 405, I contacted Jayco and this was there reply.

"Good afternoon,

Thank you for reaching out to Jayco customer service. The backers are 5x7 inches and are ¾ of an inch thick. I would not use screws longer than an inch for the backer and the weight capacity is 25 pounds.

If you need further information, please let me know!
Thank you,

I used 1/4" course thread screws as mentioned above about 1" long, and mounted a 40" tv in the front bedroom.

Hope this helps.

Yeah, I am over weight on that 50" probably, but the strap adds some support and keeps it frome so much bounce stress. Welcome to the group

Thank! This is very helpful.

Thank you. I was concerned about the TV size and weight supported so this is very helpful.

Can you post pictures of where your mount was? I am trying to mount a 40” tv as well is the same location.

I got the same email from Jayco and mounted this drop down mount. I have a 2023 4113. The tv is the 39” that came with the unit in the front bedroom.

I have traveled some rough roads and no issue.

What mount is that? Brand? Part #? Thanks much, Mike

I increased the BR tv from stock 32" to a 43". I moved it over to the right so that it would not block the doorway. Now I have to move it back 1/2" so that the slide does not hit the TV . . . Doh!

It is the MORryde TV drop down and swivel mount. TV56-129H
