I didn't know they upgraded the RAV4. Honestly I'm not disapointed with mine but not really enthusiastic about it either. I wish I had gotten something bigger at the time. But, that was in the middle of supply chain issues andI got what I could. The 'upgrade' was from a corolla that was starting to develop a 'personality' -- I wish I could have afforded and that it was available something like a 4runner. If I were in the market, that would be what I'd be looking at today.
Sounds like you drive pretty much like me...a grandpa. If I'm in a hurry and not towing, I'll do 10 over. But generally, I tend to be at the speed limit. When I'm towing, I pretty much stick to 60. We're pretty much pure flatland around me. Where the Rav4 struggles is the undulating land west of here in Wisconsin, Iowa, and South Dakota. That up-and-down, up-and-down terrain really makes it work. There, I usually travel around 60 mph, which, if you've ever driven across the Dakotas, isn't fun.
Now, in the Jeep, outback (2012 H6) and the van -- speed limit to speed limit +10 even when towing. Those don't even feel it.
