Dump Tank Extension Needed

My travel trailer has a gray tank dump handle that is under a slideout so I can't reach the handle unless I crawl under the trailer. Is there a pole for sale that can grab that handle so I can reach under the slideout and open the tank? You would think Jayco would have come up with a better design. I think they should change the names of Jayco trailers to Thor now so that everyone knows the quality they are getting. I have a drain fly infestation and they say leaving my gray tank open may be the cause.

Edit: I've seen replacement rods that are longer, but I don't want a permanent solution like that. I want a handle about 3 or 4 feet long that can grab the original handle. Maybe I'll have to make one, but attaching the grabber to the pole may be tricky unless they happen to have matching threads.
