Can a 12 Extender be Used to Tow a 3,000 lb Trailer with a Class A Motorhome


I am towing a 10’ utility trailer with a Smart car in it, approximately 3000 lbs behind a class A motorhome. I would like to add a 12” extension to my receiver thereby adding length to the trailer tongue. Do you think I’m okay by doing this?


Expert Reply:

Any 12" extender that would fit your application will reduce your overall hitch weight capacity. The Reese Hitch Extender # RP11003 (14") will reduce it by 35% while most others will reduce it by 50%. Options like the Curt Hitch Extension and Reducer # C45048 that you referenced are meant to fit a 2-1/2" hitch receiver and are typically used for a pickup with a camper in the bed.

If your trailer hitch and Class A are rated high enough you will be able to tow your trailer and car with a total weight of 3,000 lbs using the Reese extender. For example, if it is 5,000 lbs that will give you a reduced weight capacity of 3,250 lbs and a reduced tongue weight rating of 325 lbs.

Another possibility is to use an extended ball mount like part # 80232 which is 15-3/4" long, has a 6,000 lb towing capacity and a 600 lb tongue weight capacity, plus it will not reduce the weight capacity of your trailer hitch.

If you choose to go with the extender (ass opposed to the long ball mount) I recommend checking the weight ratings of your trailer hitch and your Class A (the lower will be your limiting factor) against the loaded weight and tongue weight of your trailer to make sure that you can safely accomplish this.
