Hi all, I hope this is the right section for this post. I was wondering if the Ram Promaster is capped at 5100 lbs. towing? All my research says it is, but I wanted to make sure there are no other engine options available. I'm looking for models between 2015 and 2017. Are those the same as the 2019s and 2020s or have they made significant changes to the engine since then?

Thanks.
