the other day was 94 degrees out. rv just livable 78 to 80 degrees inside. had to get something out of underbelly pass thru storage. opened door was really cool inside there. where is the cold air coming from. furnace return in step. went to lowes got magnetic vent covers and covered return vent. replaced all floor heat registers with adjustable ones and closed all off. makes a difference for sure.
