Answering your question, my thoughts on your top 5:
Window visors - are usually for smokers, hate them.
Trunk dividers - I organize differently and have no need.
Bed carpet - wouldn't work for me, I use my bed too often for home improvement stuff.
Stop dropseat thingies - I'm intrigued.
All weather mats - absolutely!
Not that you asked, but my must have list:
Bed cover (Bak Revolver)
All weather floor mats ( 3d Maxpider)
Splash/mud guards (Honda)
Bed rail system
Idlestopper
This combo:
Battery Backup & Air Compressor Plug and Play
And because I really hate the rims that came with the 2020 RTL-E, I upgraded to Honda's Diamond Cut Alloy rims- shouldn't be a must have, but I really hated the originals.
And due to idiot thieves and today's supply line issues, the nolo cat guard plates. Normally this wouldn't be on the list, but people suck
There are others I have, but these are the top... I 🤔 think.
