Question:

Hello, my name is Kirt. I am wondering if the Part Number: e52ZV High-Low Adjustable Adapter would work to extend my hitch on my RV to a 6000 pound 20 foot box trailer with our SXS in it? I see most of the information about a flat tow of a vehicle but Im looking for this other application. Current hitch is tucked under a bit and when turning to tight on passenger side, I rub the ladder on back of RV. Looking to extend but get the same or better rating on towing capacity. Thanks. Kirt

Hey Kirt, thanks for reaching out. The etrailer High-Low Adjustable Adapter # e52ZV is only for flat towing a vehicle behind and RV, and cannot be used for towing a trailer, so that won't work for you.

We do have hitch extenders that can be used for trailer towing though. For example, the Gen-Y Hitch Receiver Hitch Extender # GY89SR fits a 2" receiver and has a 10,000 lb towing capacity.

The big thing to keep in mind here is that using a hitch extension reduces your hitches carrying capacity by half. So, for example, if the hitch on your RV is rated for 5,000 lbs, you'll be limited to carrying only 2,500 lbs when using the adapter. Even though the adapter is rated for 10,000 lbs, extending the hitch puts way more leverage on the receiver, so the carrying capacity will be pretty limited.

Honestly, for a 6,000 lb trailer, towing with a hitch extension likely would not be safe or practical. A better option is using an extended ball mount like part # D-26. This is 12-5/8" long, so a few inches longer than most standard ball mounts. That should give you the clearance you need without reducing your carrying capacity. The # D-26 is rated for 7,500 lbs, so more than enough for your 6K trailer.

The # D-26 give you approximately 8-1/2" between the hitch pin hole and the closest edge of the ball platform.

Do you think that would be enough for you?

Jesse M, Thanks for the quick turnaround on this question. I use a hitch on my RV with the torsion bar configuration (side bars with chains that cradle into a hook on the trailer) to attach to the big box trailer so I don't see where the #D-26 extended ball mount has that option. Very much like what is used on a long pull behind camper trailer. Is there a standard hitch with the torsion bar setup with an extended shaft that could be an option without losing too much integrity on the towing capacity? Thanks. Kirt.

@KirtN Ok gotcha. So there are extended shanks that can be used with weight distribution hitches to create more space between the trailer and the tow vehicle. For example, the Equal-i-zer Weight Dist Shank # EQ90-02-4600 is 18" long overall and is several inches longer than most standard WD shanks. What WD hitch are you using?

@JesseM Thanks, this is what I'm looking for. The 18 inch shank is probably longer than I need but I noticed there are others in your inventory that should do the trick for me. Currently I am using the standard length WD hitch which sits in the receiver positioned just back about 2 inches (for some reason). I don't know the part number but it's rated for 10000lb tow capacity and I think 1200lb tongue weight. Can't remember exactly. Will have to double check. I think I'm going to go with the 12 inch shank extension. Thanks for steering me in the right direction. Kirt.
