i mean, most parking lots have back to back spaces, so it sounds to me like they've pulled in the first one, all the way through to the next one. I see no problem here, large trucks like this have to stop somewhere.
When I drove a small school bus, and I needed to park it somewhere in between the times I was transporting students, I generally looked for a spot at the edges of the lot to back into, where the back of the bus would overhang over the curb (I made sure it would never disturb any sidewalk). Of course, I did several times see full-sized school buses diagonally parked across 4 spaces at the far end of a large parking lot; after all, there's not much else you can do with such a large vehicle.
uh yeah, have you ever seen a moving truck? They're all large big box trucks, if you've ever been in a more affluent neighborhood you'll have seen an RV, whether towed or not. You've seen garbage trucks (though those don't really count, as do most other industry trucks)
especially considering this is relevant to ikea.
like i'm cool with bitching about f150s being large and shit, but trucks that are 22 feet long are a bit of a different story.
My friend and I used a Uhaul to move cross country once, and it was hard enough for us to park places along the way, and we could mostly fit into normal parking spaces IIRC.
We had considered also pulling a trailer, but I have no idea how we could have gotten food in towns, parked in crowded lots, etc. It would have been a lot more planning if we had a longer vehicle.
