They do. Check the shelves at your local WalMart :-)

I think the bad reputation comes from the F150 owners who have 0W20 recommended by Ford. 20 weight oil starts to sound like a bad idea when your engine has been outputting 150hp for the last 10 minutes pulling 12,000lbs up a 8% grade... Worst case scenario for sure but its hard to change your oil when you're half way up...
Most of the time engineers get trumped by the bean counters so I don't always think what is recommended is always best. It is a good place to start though for sure.
If I were you I'd keep using the 0W20 unless you get a 28ft trailer
