I still have my pinbox level from my last 5er, and for my new sabre I just keep 4' level In the basement. But I've only had to level our camper about 6 times since we got it in may since we have had a seasonal site since June.
If i was towing and setting up my camper all the time, I would just pull my shroud and put my pinbox level on. I'd rather have the convenience than be concerned about how pretty my pinbox is. I mean how often have you said " that is such a nice camper, but without a pinbox cover, I'd never pull it"
