3 days in Georgia, over 100 degrees, & we couldn't have enough LARGE fans & even small individual fans. The heat was still so unbearable that I covered the windows with aluminum foil & closed the slides. I didn't have covers over the vents above, but I will be buying them for our next trip. On our drive home down to Orlando, the highways were littered with tire treads, & unfortunately we also blew out a 2 yr old tire on the tt. So make sure you have a good spare tire & an accessible jack.
