I am in the process of buying a Highlander to pull the 2018 Jayco identified above. I don’t have the Highlander yet. I need to pull the Jayco from South Carolina Where I bought it to Richmond this coming Friday. The private seller has been pulling it with his Highlander but correctly points out that the hitch he has been using probably won’t work for the sierra pick up truck The private seller has been pulling it with his Highlander but correctly points out that the hitch he has been using probably won’t work for the sierra pick up truck because it would result in the ball being too high. I have looked some on Amazon at adjustable hitches And I’m thinking that might be the way to go since I won’t get a chance to match up the truck and the hitch and the pop up until when I get down there on Friday. Do any of you have any thoughts or recommendations for hitches.
