Common misconception, but you do not, and a folding trailer hooked up to a car with a tow rating capable of pulling it takes up much less overall space when it's folded up than the truck will most of the time. You'll also probably get better gas mileage, which is a bonus, plus better pedestrian safety, less force going into a car crash which collectively makes everyone on the road safer, and makes it safer to crash into stationary objects, decreased roadwear, things of this nature. This sort of trailer setup is done all the time in europe, as another comment concurs.
I'm not putting 3000 lbs of beer bottles on a trailer behind a (modern) car. It's borderline unsafe and over car capacity. You're talking to a CDL holder, I do know s thing or two about pulling trailers. Cars domt have full frames anymore, that's only one of the many reasons this bad idea
Seems like it. Or maybe you've no sense of scale, don't know what you're looking at. Max tongue weight like that, a person would nearly have to balance 3000 lbs on the trailer axle, 1800 front, 1200 rear or so. Recipe for a whipping trailer.
Said three thousand pound load, that does not include the trailer. Gross weights gonna be 4500, 5000 ish. Vans are generally pickup truck drivelines this continent, so no real difference there for mileage.
