Walking on the roof

Have a 21BHS on order and am qurious why you guys are installing these vent covers? Weather, debris or areodynamics? Or is it to vent while traveling?

It also helps if you accidentally leave a vent open and travel because it can easily damage the vent.

[font size="3"]What TinkeringTechie says X2. Also lets you leave the vents open when you leave the trailer for day trips. No worrying about rain.

Thanks. Another good idea.

[p]Ditto for the above. And, the OEM vents are made of very thin plastic and over a period of time the UV will make the plastic brittle. One winter we had an enormous amount of very wet, heavy snow piling up on TT's roof and I couldn't make out the location of the vents. I used a small plastic shovel to clear the roof and accidently hit the vent, not very hard, but hard enough and shattered the entire side of the vent. The Maxx Air vent cover is manufactured of much heavier plastic and is more resilient than the OEM vent cover.[/p]

I got up on my BC16FK Roof last week as there was no way I could mount the middle Camco Vent Cover. I didn't stand on it, just sat or on my knees and hands. Roof felt very Solid. I weigh 225.

205 pounds! Walked on my roof! NO DEFORMATIONS, dents, wrinkles that were not already there.  I wear a size 11 work boot, so maybe 10 square inches of sole.  That makes 20 pounds per square inch when only one foot is on the roof.  It ain't thin and it barley flexes in the middle between trusses.

I would say no jumping, running, etc. but working on your roof is fine.  

The roof is OK to walk on, just don't go crazy up there and have 3 people standing right next to each other. NO dance parties or family photo session.

It really can't be good for the camper. This looks like it was at a rv dealership or perhaps the Northwood manufacturing facility. In either case -- people who should know better!

Well that's just plain dumb. Looks like about 30 people so there's  probably well more than 2 tons on that roof. I'd like to see the photo taken right after this shot!

I've walked on the roof of my 21BHS with no problem.  I weigh about 200 pounds.  Normally though, if I need to get up there, I throw some sheets of plywood up there to distribute the weight.

The vent covers on my 21BHS all cracked.  I replaced them with the CAMCO replacement covers.  They are MUCH thicker and more durable.

i just replaced 2 of the fans with fantastik vents.  both of the cover had cracks in the edge where the indentions were.  the 3rd cover i had to replaced after resting my hand on it (during the install of the other 2 vents) at which point it pretty much exploded.  my vrv is a 2013 so i was surprised they were so brittle after just 2 years.  i replaced that 3rd hengs with a smoked hengs replacement.  it seems like a different material but will probably only last 2 or 3 years as well.  at least they are pretty cheap

here is a link to the replacement from hengs  http://www.amazon.com/gp/product/B0027XK7OW/ref=od_aui_detailpages00?ie=UTF8&psc=1

hey dj...what was the camco part number that fit the hengs fan?  thanks

I think it's the 40148 smoke 14"x14" universal vent cover
