Alrite not trying to derail thread but no one has responded on here since 3/3/19 . Just a quick comment : I have a steel 8.5x20 v nose Continental 2005 small car carrier thats been great . A couple days ago I go to checking and knowtice the plastic roof vent on my 14x7 cargo (Ariseing) 2018 completely destroyed /cracked etc . Called trailer headquarters and they said part out of warrantee (been over a year). I wasnt trying to nickle and dime them but felt this part even in Fla sun should last over a year . On my 2005 Continental i have yet to replace my roof vent covers (2) . Anyhow i ordered this steel 14"x14" from
https://www.amazon.com/Ventline-BV0...er+roof+vent&qid=1560812584&s=gateway&sr=8-10 looks well made . Plastic vents were like $17 . This one was like $22.50 plus tax with Prime . The one I bought claims to be aluminum , to me it looks like galvanized steel, way heavier than the plastic also . Been rainin heavy here for a couple days . When it breaks going to install new one . I dont care if the steel one is darker inside or what but as for me I wont ever buy a plastic cargo/camper roof vent again 14"x14" . I felt like the cargo vent they put on mine I got a bad run of plastic , or what they are kicking out nowadays too cut corners is cwap !
