Question:
I have a 2021 Ford Explorer Base- 2.3 Ecoboost I4 engine. I also have a 17.5 foot travel trailer. The trailer weighs 3000 lbs loaded. The towing capacity for my Explorer is 3000 lbs. I only two the trailer once a month about 6 times a year to the beach two hours away. Do I need to up the situation with a oil cooler set up? or a larger radiator fan? Everything I read online states nothing definitive. I guess my point is... what is a reasonable solution and what would be total overkill? I also have not purchased the hitch yet but would do so here with you guys. Dp you also sell the other items??? Thank you Sincerley Robin

Hey Robin, thanks for reaching out. We do have a solid hitch option for your 2021 Ford Explorer: the etrailer Class 3 Hitch # e29YR. It’s rated for 6,000 pounds of towing, but just keep in mind that your Explorer’s own 3,000 lb limit will still be the governing factor. The hitch gives you the strength and durability you want, but the vehicle’s rating is always the final word.
Since you’ll be running close to the upper end of your Explorer’s tow capacity, adding a transmission cooler and possibly a higher-capacity fan would be a smart move to help keep temperatures under control. Unfortunately, we don’t currently offer a trans cooler setup for the 2021 Explorer, but it’s definitely something worth looking into locally.
You might also consider tightening up the rear suspension to keep things level and stable under load. Our best option for that is the Air Lift 1000 Air Helper Springs # AL87CD. These sit inside your rear coil springs and can be aired up as needed to add extra support. They do a great job reducing sag, and that helps with stability, handling, and braking - all things you’ll appreciate when towing near the vehicle’s limits.
Let me know if there is anything else I can do to help!

Hey Robin, how did things go with the hitch and the Air Lift helper springs on your Explorer? Did the setup help keep your trailer stable on those beach trips? Your update could make it easier for others towing near the same weight range.
