On the CR-V, 2014 was the last year you could tow 4 down. For the 2015 model year they switched to the CVT transmission which is not towable.
I have a 2014 CR-V bought in Dec 2017 as Honda Certified Used with 38k miles. I have towed it 16,000 miles so far. Itís also my everyday driver.
You may be able to still find a good used 2014. Not sure about the last year for the Pilot before they switched the transmission. Seems like everyone uses CVT these days and there are very few 4 down towables.
