    I have a 2019 Southwind 35k, at about 50 mph it has 

    a vibration and gets better at 55. Had front wheels 

    balanced twice with no change. Any ideas?

    I had a similar issue on our coach. After a number of tries at balancing, I found a shop that specializes in large truck tires. They spun the tires under a load and the problem showed up immediately.They found broken belts on 2 of the tires.

    I had the same on our flair. Had the front tires balanced and they found the steering stabilizer was bad ( common on F53 frame) and did an alignment. 
    Ford Superduty trucks has had a problem with this, and there was a recall on F250 and F350 units. It has been called the “death wobble”.
