Easy, but essential addition for any travel trailer: putting a big level on my travel trailer

My older son helps as I add a Level Master level to the front of my 2021 Grand Design Imagine 2400BH.

It's really nice to be able to check your mirror as you drive into a campsite and see how level you are. Often you can watch as level improves or worsens as you go, and you can change your approach accordingly. Less times getting in and out of the truck. Less guess and check.
