OK now all the others have spoken. Maybe ONE has had your problem, THAT one being me!!
I had the same thing happen on a Sunday night, on I65 n in Birmingham, Al. The only thing that can b done is to tow on 3 wheels to a safe parking spot. 2 locate a repair service, tell hem what your problem is, check to see if they have a/an axle. 3. If so tow your disables RV to them, or tow it to them and wait on a new axle and parts.
THERE IS NO WAY IN HELL they have any way to carry it there, IT WILL NOT FIT ON A roll back, or low boy trailer.
This is experience, speaking, I had ith a CrossRoad Crusier. Took 6 week for warranty parts.
Sorry for your problems but sometimes there is really things that are not that easy to fix, PS the new axle lost same position set of bearing 3 months later with less than 1000 miles.
GS did their best on the 1st BUT never got help on the 2nd in the country on a two lane road with me blocking the road.
Guess the naysayer will say it was my fault as I DID not redo the darn bearings myself.
