Looking at purchasing a 2020 Mack Anthem, any concerns?

Yeah, the bed is kind of high regardless of mattress. On the other hand there's a ton of space underneath it.

I'll look at my wiper blades today. Mine has whatever came on it. They don't cover much of the windshield compared to other trucks I've driven but they don't rise up on the ends, whatever they are.

 

Being Canadian it’s been my habit for years to run factory size wipers in summer and 2 inch shorter in winter with the size of windshields in modern trucks I find wipers build up ice way too fast and lift off window with the factory size the slightly shorter ones last much longer before you need to clack them to remove the ice overall visibility is better due to a cleaner sweep.. long cold stiff wipers leave more film residue on windows which requires more washer fluid which in turn messes up side mirrors lol
