As someone who’s hauled several makes and models on several trailers (none of them being uhaul) here’s a few tips to keep in mind.
-Our cars are fairly low, so consider that when picking a spot to load. Ideally back the trailer into a driveway transition or up to an accessible curb to reduce the difference in deck height as much as possible so your front bumper doesn’t scrape the ramps.
-Always load forward. Tongue weight is key, because with too much weight aft of the CG the trailer will sway and become harder to control the faster you go.
-If they’re available always use tire straps or strap through the wheels. This allows the suspension of the car to bounce as much as it wants without the possibility of the straps falling off (hard compression + already loose straps = possible chance for it to fall off).
Not always practical or available, as you’ll see in my pictures only the mk6 is strapped through the wheels, but that’s definitely the preferred method.
-Always check your straps! My usual method is to drive a 1/4 mile or so then stop to re check everything. Any misalignment will start working itself out pretty quick so rechecking right after you leave is important. Depending on road conditions check again every so often, at the very least every time you stop for food/gas ect
-Should go without saying, but check the trailer tire pressure before loading and triple check the hitch and all lights. People suck at driving and don’t give you extra room just because you’re in a big truck and trailer so being sure everything works as it should is cheap insurance from being hit or stuck on the side of the road somewhere
