Depends on how good the roof keeps out water. Mine does a pretty good job. I only had one mysterious drip that I couldn't figure out after and entire day of rain. I have a 2008 Jayco Baja.Some great advice in this thread. We're hoping to be first time attendees this year!
Is it pretty popular to haul up a pop up camper? With all of the comments about rain and wetness, I just wanted to see how the pop ups hold up versus the elements?
