Looking at adding portable solar panels. Have a 2019 26 ft trailer, any ideas on how many watts i would need? And reliable brands.

Would be very rare to actually get 400w out of 400w panels mounted flat on the roof and have battery low enough to need that much.
How many amp controller are you using? The kit that is being delivered tomorrow has a 40 amp kit. 400/12 = 33, so not much cushion there and the next biggest controller was pretty expensive.

You need enough to replace what you are using plus roughly 10%
How much was that for you? I'm about to install 400 watts on my rig to get started.

400 watts is probably fine for most people. My 675 works fine on my 26' trailer.
Sometimes going big from the start is lower cost and better for ease of use.
A patchwork of small panels so that you eventually just barely have enough can turn solar into a multi year project that never really just works so you can mostly ignore the battery charge level.
