I have a Scania K92 with the original Air conditioner unit on the roof. Find it leaks in wet weather as well as in humid weather when operation. Drains are all in place. Coachair unit works like a charm.

Henry.
It'll be like any Caravan and truck.
They need resealing every coupla yrs.
The vibrations and stresses of hauling up and down the roads cracks.moves, Dries out the sealants.
Lift it up and reseal round the Gasket. Preferably with "Silastic",
Unless they have proper gaskets for them?.
Those Coachair are about the best too. Caravan We had b4 last one is near 30yr old now.
The Coachair I fitted is still running he said earlier this yr.
If you haven't got high garage roof to run blocks from.
I got two TALL tressles with coupla 10ft planks
side by side alongside of van on each side.
Planks across.
Blocks from planks.
Just hoist it, Block. reseal and drop down again.
I've used those tressles from Broons for all my panels on roofs so far.
Cheap and SAFE.

macca,
I have tried unbolting the unit but it dont seem to want to lift. I might give it another go, using timber wedges. I didnt want to put too much stress on it in case I crack the gas pipes.
BEFORE you do anything Henry.
Go on Coachair net page.. Manuals.
and upload a copy for your unit.
If not. Find Ph no for them or agents. And ASK. if you don't know.
Anything I'm doing and I can't find unfo on net.
Nearest Workshops for that model
"Wksp Foreman please"
Hey. Nice day.
What can you tell me about ??????"
Attitude is Everything.
You nice. they normally reciprocate. Normally.
some unfortunately, are pricks.

Hi macka, Yes already done that. Got onto the guys from Coachair. Very helpful. (See reply below )
Good afternoon Henry.
Unfortunately water leaks are never easy to identify the cause and location as there are so many areas water could enter through. If your a/c lids are not cracked and sealed then the water won't be entering in through the inside of the a/c . It would likely be from the mounting areas such as where the unit is bolted down of the seal around the holes in the roof located under the a/c. If this is the case then it would be difficult to repair as to do the job right you would need to lift off the a/c pod clean the areas and then reseal. But it may not be from this area , you would need to determine where the water is entering by using a pressure wash gun and spray around possible areas. Another common area for leaks in the roof is through lights and antennas.
Might have a go at it today, before the predicted wet weather comes in this weekend
Thanks for your assistance.

If you not too fussy about fancy smooth looks on roof of your rig.
Get a dual tin pack of heat reflective paint.
OR 4/6 ltrs of Pool Paint/ Chlorinated rubber.
We use it on steel boats under water.
Both are flexible.
Dig out most of the crap along seals and folds on roof.
After a scrub down. Hard scrub over with acetone.
Run around with tube of Sikaflex filling all seams and holes.
Then Brush/roller either all over roof and seams.
Takes a coupla days but well worth it.
will seal and waterproof roof real well, for a few yrs
But really. You should be resealing seams in walls and roof.
every few yrs (2 or three) on corrugations,less.
Apart from that. Get a big tarp, cover front of roof.
. park in one spot till wet gone. then reseal roof.
You can't leave it. Plus if it all a real solid installation and you didn't make the rig..
Resealing is best way of masking/sealing a prick of a job
till you front a coachbuilder somewhere and get his advice..
Other advice is seal it off. remove. fill hole.
and fit one or two LG Household split Inverter systems, front and back.
They magic and run easy for nothing.
When we travelling in caravan and Landy 50 yrs ago.on Construction sites and pipe lines.
I repainted and resealed roof and side seams of my van every yr. (22 fter)
Ser 1 Landy.
1.5ltr side valve engine, full time 4wd Just H/Low lever.
Towed that van all over England.Wales and Southern scotland.
Never missed a beat. at 25ish MPH. around 10/12mph up hills sometimes less.
Was struggling to do 35/36mph full bore (ha ha) with a tail wind but went everywhere.
Found it in back of farm yard shed on blocks chucks roosting in it.
Paid 5 quid. plus another 15ish. and it was reg'd on road.
Wish I had it now.
Have fun.

sounds like your a patient man mate, lol. landrovers are slow enough as it is. Yes the ac unit works just fine other wise I would take it off. When it packs it in I will install a split.
