waiter Posted January 9, 2011 Share Posted January 9, 2011 The Original Vents were cracked and leaking and needed replacement. New vents can be had for about $35 each. Try and get the ones with metal flanges, not plastic. 1) Right after I bought the MH, I did a quick and dirty patch around the vents and seams. This is the stuff that Deans RV recommended. I painted this stuff around all the vents and outer seams just to last me until I had the time and a place to work on the roof. 2) Even though I did a good job on the temporary patching, I still had a very slight drip. Only after watching carefully did I discover the water was sneaking past cracks in the plastic flanges. If you doing a roof patch, and you have plastic flanges, make sure you look at them for cracks. 3) I used a putty knife to expose the screws. 4) After the screws were removed, the old vent pried out. I cleaned the original sealant off with the knife, then used Lacquer thinner to remove the sealant from around the opening. 5) I laid down a 1inch wide butyl tape making sure it covered the old original holes. I then screwed the new vents on. I used #10 Self Piercing 1 inch hex head screws. 6) After I snugged all the screws, I used the putty knife to cut off the excess. Note - The four old corner holes are not being covered by the new vent. I put a small amount of sealant on a screw and just put a new screw in the old corner holes, just to cover the holes. 7) Two new vents and a TV antenna (NOTE - The sewer vent is just sitting there, that's not really the sewer vent location) 8) The far aft sewer vent was non-existent, this is removed and cleaned up. Because the sewer vent is trying to mount on a curved surface, I had to double up the butyl tape on the very bottom and very top to fill in the gap. This area will be painted with the white sealant when I do the rest of the vents. 9) The new aft sewer vent, Not you can see the new aft roof vent also. NOT SHOWN YET - I'll use the white self leveling sealant and a small paint brush, and paint the white sealant over the flanges and screws. I'll get a photo of this tomorrow when I finish. I still need to replace the screws in the Luggage rack, and then I'll reseal all the screws. Quote Link to comment Share on other sites More sharing options...
waiter Posted January 10, 2011 Author Share Posted January 10, 2011 Finished on the roof. All the vents replace. Installed a TV antenna, replaced both sewer vents. replaced the screws holding down the rack and resealed. 20) A finished roof vent, sealed, and good for another 10 years 21) View AFT. Universal Refrigerator vent cover - replaced the one that was missing. The dark vent I did not replace, It was in good condition, no cracks, and has a powered fan TV Antenna toward the front On the vent all the way in the back, One of those fancy covers so you can leave a vent open, even in the rain. 22 ) View forward 23) Note the vent cover mount plates (The vent cover does NOT mount to the roof directly, but mounts to the flanges that are installed to the vent frame.

dayoff53 Posted January 10, 2011 Share Posted January 10, 2011 Thank you for sharing! This kind of project is much less daunting if someone else has made a good record (with pictures!) of what they did for reference. Quote Link to comment Share on other sites More sharing options...

Derek up North Posted January 14, 2011 Share Posted January 14, 2011 I want to remove the Coleman a/c unit on mine and put a vent or bubble top. Make sure you spend a few extra $ to buy a good vent with a good fan. 'Fantasic' is one make that's popular, though not cheap. You'll just have to fish up a wires with 12v plus a ground. I've got a Fan-tastic (6000RBT) fan in my Warrior over the bunk. It moves a lot of air and is quiet. In the bathroom there's a vent with a small, noisy fan in one corner of it. Though it only blows/exhausts, it really 'sucks'. http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dautomotive&field-keywords=fantastic+fan&x=16&y=17 A MaxxAir vent cover is nice too, since you can fully open your vent(s) even when it's raining outside. http://www.amazon.com/Maxxair-00-933066-Translucent-White-Cover/dp/B000UUMM6K/ref=pd_sim_auto_1 Quote Link to comment Share on other sites More sharing options...
waiter Posted January 14, 2011 Author Share Posted January 14, 2011 I installed one of the MaxxAir vent covers over the Bathroom vent. With the MaxxAir cover, the vent does not open all the way, it opens about 1/2 - 3/4 This isn't a big deal as the vent surface area is now limited to the MaxxAir opening. The Black vent is where the AirConditioner would be installed on my Dolphin. Its all wired up and even has a thermostat (it controls the powered vent) I would have rather installed the MaxxAir on my vent that has a blower (the black one in the photo), but this vent has a plastic frame. Probably would have been OK, But My intentional use for the MxxAir is when I'm traveling or just to leave a vent open long term when the ToyHouse is not in use. The MaxxAir are cheap enough, I may go ahead and put one on the black powered vent anyway. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted January 14, 2011 Share Posted January 14, 2011 Just don't hook the Fan-tastic fan to 110v or it'll suck your toupee off. Quote Link to comment Share on other sites More sharing options...
