thinking about possibly going in the mountains for Xmas vacation. Would likely take the trailer - a popup. We'd probably try and find some snow to enjoy. But I've never trailered in the snow. Popup is pretty light (about 2,500lbs or so I think) but it has dinky little skinny kindaworn tires. Popup has electric brakes. I'd rather not have the thing dart sideways the whole time or make it impossible for the cruizer (not sure which yet) to brake. Advice / comments?
