Self installing a slide out topper

I have a 2019 Forrest River Mini lite and the slide out doesnít have a topper. I wanted to save from a dealership installing one and thought I would order one and do it myself. My concern is drilling any holes in the side wall of my RV and messing something up not knowing where any supports are. So my questions are this.

1. I watched a video on Utube and they just attached the topper wall rail right to the side of RV with screws it came with and didnít feel they hit any supports, so will that be enough to support the topper mounting rail to the wall and not come out of the fiberglass?

2. I am a decent handy man, is there any reason at all I shouldnít do this myself and just pay a service department to do it for me?

I'm a newbie (bought in June) and just installed the slide topper with little to no issues. Have a helper and take your time. Measure multiple times before drilling...:-) and you will do fine. Purchase what you need (sealant, etc.) before you start. We took our time and finished in an hour and a half.

I too installed my own. Carefully follow the instructions and not only have a good helper, have two good free-standing ladders.

If your's is anything like the one I installed it's designed so the brackets are merely mounted with screws into the siding and any reinforcement that might be behind it at the top edge of the slide. There are about a half-dozen screws for each bracket so no one screw is heavily loaded. Whatever you use as sealant will also act like an adhesive to hold the bracket to the side of the slide.

Like I said, just follow the instructions.

If memory serves, I believe all the screws are self-drilling.
