I second this, also I lived up in Northern Illinois/Chicagoland and never had an issue with salt on the factory wheels. Wheels are the least of my concern when it comes to salt damage.
Undercover ultraflex here. I will always have a hard folding that allows full bed access. I went with the ultraflex because it has arms to keep it upright for full bed access, I did not like the idea of it riding on the cab even if there is padding.
I have learned always file a claim. Got rear ended at very slow speed in my BMW which did not appear to cause any damage other than a scuff. Filed a claim and they found the exhaust was bent slightly and there was a broken bracket as well. Ended up being over 2k and my insurance went after them and I got my deductible back.
GM accessories has rear seat infotainment. An iPad and tablet mount would be cheaper though.

I have the ultraflex and would recommend it to anyone. Great customer service as well. I was missing a clip on the support bar when it was delivered from Amazon and they fedexed me a bag of them. Recently I broke the little retainer clip that hold the support bar against the truck bed rails and again they fedexed me a bag of them.
Damn, where are you parking that you are concerned about people smashing your windows? Most of the time cars are "broken into" they are really just left unlocked and someone gives the handle a jiggle, "breaks in", steals what they can sell quick. Lock your truck, have an alarm, don't park in shady areas.
I have the undercover ultraflex and love it. No leaks and great customer service. I ordered it from amazon for shipping, but have had a couple small issues (bracket that holds arm in place and the latch on the arm) and the manufacturer sent the parts no questions asked fedex 2 day.
Curious as to what makes you say Tesla are crap? I have many friends with them and all love them, and the new long range models have 8 yr/120k battery and drive warranties. Now sure I have seen some issues in workmanship, but for a model Y you are getting a full electric vehicle for ~60k with all the options aside from the factory performance upgrades.
