Rapido 665F Roof Pond

[stevec176]

My wife and I recently purchased our first mototrhome, a Rapido 665f, and are generally thrilled with it except that a pond forms on the roof whenever it rains and doesnt drain away. At the rear of the van there is a channel running acroos the roof which is preventing the water from running away so a large pool forms in the rear nearside corner, just where the aerial is fitted. The water only runs away when I move the van and then it pours down the front down the cab door which can be a bit of a problem if you open it. Has anyone else had the problem and how was it resolved?

We get a pond on the roof of our Burstner and, from what I've read on forums, it happens on other vans as well. The only solution I've seen suggested is to park the van so that it is slightly sloping (using ramps if necessary) so that the rain runs off rather than staying on the roof.

Thanks Graham, thats what we were told when we collected van. I've tried ramps but pool still there and I'm worried about seepage through gland seal on aerial. This is obviously another stupid design fault which could easily be resolved by trimming the trunking to leave a gap. Will have to speak to suppliers.

If it is just the gland seal you are concerned about maybe an overseal bead of Carafax Caraseal or Puraflex 40 around it might protect it.

Thanks, I'll check that out but would still like to try and drain the lake before the ducks roost.
