Combo Hitch for Car + Bike Rack

[KrankyKoot]

I am a newbie to RVing so hopefully I am posting this in the appropriate discussion area. Does anyone know of a combo towing receiver that will allow me to tow my car dolly and hitch mounted bike rack and that will also allow me to disconnect car dolly without removing the bike rack?

I have tried a dual extension receiver with a 5 1/4" drop ball insert for the dolly. Works like a champ but is almost a foot longer than safety chains, electric connector. Yes I know I could buy extensions but it adds more length than I would like.

My current solution is a combo unit with a hitch receiver on top and ball on bottom with a 2" drop. There are several on the market from Curt, Conner, etc. but all with the same drop. I like this better but need to take bikes down and pull rack to disconnect dolly.

So my question: Is there a combo unit with a 3.5 - 5" drop? Thanks for any help or advise.

I assume you have surge brakes? I could not find a commercial one that had enough clearance between the ball and the upper receiver for our Demco dolly. I finally had a local welder cut off the top and raise the upper receiver a couple of inches. That has served us well until we went 4 down.

Be careful with extensions - the extra moment will multiply stresses that the hitch system or your RV frame may not be able to handle. This happened to a friend of mine towing a light pop-up using a Reese bicycle rack (this particular model had about 18" of extension to allow mounting four bikes above the trailer hitch). Even the light tongue wait of his pop-up caused the frame of his TV to fail (fortunately at very low speed).

Why not put a bike rack on the back of your car/toad?

I just ordered one from Roadmaster off of Amazon. It is a 2 inch drop on one side or turn it over and it is a 4 inch drop. I believe they make different sizes. They make a "lighter" and a "heavier" duty receiver. This is the one I got... https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

But if you check out Roadmaster's website you may find what you are looking for.
