Drop your trailer and your truck onto real satellite imagery, to scale. CampScan says Fits, Tight, or Won’t fit, and tells you why. Then practice backing in before you get there.
The pad, the trees, the pedestal and the fire ring are traced on the imagery. Your rig is drawn at its true size. Drag it where you would park and tap Check fit.

Park the truck on its own. Turn it sideways, tuck it behind, try the far corner. The verdict covers both.

Not on the list? Type the length and width. Trailers can add coupler to axle, which sharpens the backing sim. Your numbers stay with you from site to site.

Drive the same rig into the same pad from the road. Trailer swing, jackknife warnings and every clip of a tree, all on your phone. Stuck? Show me how plays a clean line in, then hands you the wheel.

Real pads at Yosemite, Zion, Moab, Fort Wilderness and more, traced on real satellite imagery.
Find your model or type your own numbers. They travel with you to every site.
Get the verdict. Then back it in yourself, with Show me how when you need it.
Each one opens the demo on that site. Pick your rig and go.
