I looked at the Ram towing chart and some of the payload and overall tow numbers are off the charts:

The reason I checked was the article in Camper Report which claimed to detail the BEST tow vehicles for 2021. Found the article an inane rehash of marketing spiel. They touted the new F150 without any facts, some truck I have never heard of and of course the Ram and Chevy offerings. The reason I went to the Ram site was the 1500 TRX with 705 hp. I am just guessing this may not be the ideal tow vehicle of the future or any of the half tons (or the new Ford Ranger). The Ram towing chart was an eye opener though for the 3/4 and 1 tons. Of course in the 3/4 ton listings the range of payloads was insane.
