Ray,
The only way you could have it to where you could leave it on and slide the hitch through it is if your truck has the heavy duty 2 1/2" I.D. reciever with the reducer to 2" I.D. like my truck has. Then I could make the nozzle piece out of 2 1/2" and it would then be ur reducer. But then you would need an extended hitch to reach all the way through the nozzle
