There are some issues I've noticed. First. not everyone is all that good at backing into a site. I have years of experience backing both trailers and "Single Vehicles" (Like a motor home) and some places I have to take 2 or 3 stabs before I'm happy (Centered)
Some sites you need to be "off center" to be level
And at one park.. I was dead center in a very "Flat" and level site, So was the campter next to me. But our slides both extended over onto the other site. We agreed it was not a problem and enjoied the stay.
But you had to walk a Zig Zag path past the two units.
And we were both perfectly centered
(Sites not wide enough)
Could be worse though. He pulled out and a Class C backed in. Brand new. I had to help 'em figure out which tri-mark key fit which door lock (there are two). Well they went to dinner nearby and tried to park in the structure. Which had the clearance per the numbers on the pipe.. but the pipe hangs LOWER than teh ceiling and it ripped to Roadstar TV antenna off then flew up and came down on the bathroom vent lid.. Sticker still in window.
