We have had issues with our 39' fiver at state parks. Some will say they can accommodate you when they really can't. Twice we were almost stuck just trying to get out from the campground roads after we found the site would not accommodate our fiver. We avoid state parks partly for this reason. Private parks have not been a issue.
Nobody should care what you do with your money, but maybe not being so open with your reasoning for why you want a 40' toy hauler would have avoided the controversy. You kinda opened the door so to speak. Just an observation FWIW.
