I've driven over a few bad roads with my hybrid, not by design. Taking it slow the trailer did fine keeping in mind what you have for clearance, low point on some is the cleanouts. Mostly had cabinet contents strewn around, clothes off hangers, microwave emptied and smashed the glass tray, that type of stuff. I know some who bungee the cabinets and fridge closed using various hooks and such to attach them to. We went through the trailer and secured what we could. These cabinets aren't built to take much abuse.
