Jayco Dove Roof Vent Upgrade - Best Roof Vents

When I had my caravan (Regent Series 2) it had small european style (plastic) popup vents with fluted "paper" that always fell out. I replaced one vent with a rooftop air conditioner and the other with a four seasons hatch. Just remember to always close the forward facing vent when travelling or it will get ripped off by the air pressure.

here is a picture and specs of one I found

Hi,
From your pics it looks like the timber rot is the result of water leaking in.
Until you stop the leaks this will continue to happen even after the new timber is fitted.

Is it possible to repair/replace the damaged timber and then fit an All Seasons vent in place of the original unit.

IMHO, All Seasons vents are one of the best around and provided that you can buy one that will fit the space in the roof or modify the space to fit one, that's what I would suggest.

When it comes to a suitable sealant, I would suggest that you use one of the "Sikaflex" sealants rather than a silicone one.

Be aware that "Sikaflex" also make a range of very effective adhesives that may be suitable to secure the new vent to the roof of your jayco. I'd put a few selftappers in as a security blanket as well though.


Have a Happy new Year.

Disco.

Hello, regardless of whatever roof vent you choose to fit do not use any of the silicone products, as advised in a previous post Sikaflex products are much better suited for both sealing and adhering to many different substrates, you can go into the Sikaflex website for more info, there is a huge range for different applications. As far as cleaning silicone from existing vent site ,your local hardware can probably supply a fluid, and with something like steel-wool you can abrade the area prior to fixing a new vent. The timber around the area may be better replaced with LOSP treated pine,it comes in many different sizes and generally used for exterior use in the building trade, one of the trade names is "Designer Pine" comes pre-primed.

Thanks for the info, definitely no silicone, will be urethane all the way, probably from sika. I am also removing all the other roof trims and doing them again so we should be leak free. If anyone has a specific sika product they have had success with please post what it was.

I have a heap of nyata in the shed so will be using that to make the new timber frame. Treated pine is good for termites but rots just as quick as everything else if it is wet constantly.

Stripped the old vent off today, I will be replacing it with a larger one, probably not a four seasons though as they are to pricey for my budget. I am hoping something around 450 x 450 or 500 x 500 so I can cut all the damaged roof sheet out and get rid of all the silicone coated stuff.

Also stripped out the seat frames. They are all being strengthened with additional nyata then topped with new ply, no chipboard. All the tops will be hatch style to allow top access. I aim to get rid of the front sliding access doors and replace all the rest of the fronts as soon as I can source so suitable laminated ply, in the meantime it is going to be painted with semigloss acrylic.

Pulled a wheel off to see what the brakes were today, they are only connected to hand cable brake, no towing brakes. Girlock 10 inch, can anyone tell me if they are the electric ones with the actuator removed and if so are they worth refitting with an actuator or should I just upgrade to Alko or something else?

I will keep this thread going as my Dove upgrade thread, so if any mods want to change the title feel free.

Cheers,
Mike

Hello, I have used a number of Sikaflex products,"Sikaflex PRO" is a good all-rounder if a little slow curing there is a similar fast cure sealant. With metal roofing etc you will probably require 1 of their primers, you can download data sheets from the website - www.sikaflex.com.au, go to the construction tab for full info.As far as the use or not of treated timber, have you checked the durability rating of Nyata , this too will be subject to the same conditions, but regardless of what is used, care in preparation & application of the sealants will be the determining factor to a successfull job,hope everything goes well, cheers Bill
