The change we made when we started towing the car hauler ...We don't book online without calling also unless I can pick the specific spot and it's clear it's long enough by the listing and photos or google earth views ....even then I like to call and confirm. Most online sites want the mh length only ( koa comes to mind ) but have a category "motorhome towing" .. not enough info so I call and talk to a real person AT the campground not some reservation site.
I just need 67' I don't worry about the car .. the car stays in the trailer or if I take it out it goes in overflow parking or back in the trailer ea day just like the "garage" it is
