I've been trying to find something called a wind scoop to attach to a motorhome skylight to capture any breeze and send it into the moho. They are quite common in the sailing world. See below.

I can't find anything like this for a motorhome. Obviously it would have to be modified as you would be unlikely to be able to dangle it over the hatch in the same way, unless parked under a tree. Anyone aware of anything like this?
 
Looks like it would be a right faf to fit. Why not just fit a Fantastic Vent.
 
Well, price for one thing, weight for another........ I may well end up with a Fan-tastic vent, but so often traditional style solutions work quite well too. Just wanted to see what's around, if anything.
 
Looks as though you would need a mast and rigging on the moho to attach it too! :unsure:
 
The trouble with motorhomes is that they are not on the water where there is more of a breeze to catch, you could put the Heki lid right up and it will catch some air if it is facing the right way, but in my opinion you are better off with a powered vent, give a bit of thought to opening windows on the "cool" side of the van and you can manage the heat quite nicely.

and shutting curtains/blinds on the sides of the MH that are in the sun's glare.
But remember to move them aside to look at the view :eek:

We bought our MH late August & after 'practising' on the drive it was quiet autumnal by the time we got to a campsite so we've all the keep cool tips to gather.
We did OK at keeping warm in winter :) Our gas heater on low settings (:h:) kept us cosy overnight & at 3-4 was toasty for dinner & chilling. But that's OT :eek:
 
Whilst travelling, I fix the rear vent up to draw air through the van and that seem to work. They will not hinge the other way (unlike on caravans) but I think they would get ripped off by the wind (or a low branch) if they did.
Whilst stationary, reduce heat gain with screens. A fantastic (or similar) is good, but may not be essential.
 
Hot air rises so you want the roof vents to be used for expelling air. Unlike a yacht a MH has big side windows and a door or two. Open these and then open the roof vents and use an Endless Breeze fan to aid circulation inside the vehicle. :)
 
Expect you're all right. Barking up wrong tree. I expect something could be bodged up but probably worse than some of the suggestions above.

Have Dometic bought the rights to the Endless Breeze? The Dometic brand item looks like the same thing?

One of the best things we bought for our van was a 'Solar view' screen,keeps the heat out,people can't see in (unless you've got the light on at night :oops:) but you can see out.

Silver Screens the original and best Motorhome cab window insulation !

'Silver screens' from J&M Designs (01274 872151) Mike Parker and June Richardson are the original inventors of Genuine motorhome 'Silver screens' and are the only company who can legally use the trade marked 'Silver screen/s' name. www.silverscreens.co.uk

Doh. Should have Googled first. :giggle:
 
If you really want a scoop, B&Q do a canopy for a hot tub for £30, which might be adaptable on the roof. Alternatively, we have a Maxx Fan instead of the middle Heki, which is superb. Oh, and two computer fans in the upper fridge vent to keep the air cool.

I thought commuter fans were only to be used on a train?
 
Thank you, corrected. Blurry predictive text!
 
We have downsized now to a much smaller wagon, we now have a Warwick Duo, which we love, we bought a place in Spain and it is wonderful for the trip there and back etc., we also installed a Viesa Holiday 12v evaporator which is excellent for the Spanish heat in summer! We love it because we are totally independent and only need to go on site every 4-5 days for water, the solar panel and that mean th1at we are happily cool at night! Apart from putting our own swivel seats in it is the best thing we have added
 
If you can afford it get fit a maxfan deluxe fantastic piece of kit

Be careful what you wish for.

I opened our electrically powered Remis 'Heki type' rooflight right up when surveying the solar panels.
It goes in next month to fix the non operating 'down' function of said rooflight.
Doh!
 
I got a piece of acrylic cut a hole in it for a 220mm computer case fan wired with a variable switch to the nearby light and fixed it into our rear roof vent above the cooker.
With the other roof vent or windows open works a treat.
Don’t think it cost me more than £10:00
 
Maxfan is brilliant. Fitted ours a couple of weeks ago and gave it a few tests last week in the heat and then a proper test this weekend whilst away in the van. Really really happy with it, and is quiet enough can run it whilst asleep.
