welcome to the forum!
unfortunately I do not have your brand or model but do own a 5er !
you may notice with kids that your camper may have fore and aft movement . almost all do ! And to put it lightly its ANOYING ! I M O invest in a stabilizing system the mounts to your front and rear jacks to eliminate movement .
suck as steady fast or any other company that makes them.
I made my own out of trailer cargo holders look at attached pics .
they make a hugh difference !
that would be one of my top purchases that I don't regret !
