Hymer/Kampa Awning Problem

Hi everyone, I'm after some help please.

I have a 2007 Hymer Nova 545 and when I bought it, 6 years ago, it came with a Sunn Camp porch awning. Although very lightweight this worked well until, suffering from UV damage, it quite literally fell apart 2 years ago. Having been impressed by the Kampa
range, I replaced it with a Kampa Rally Pro 390, last March, purchased from Norwich Camping for £377.96.

When I first used it in the rain, during a 2-week holiday in Devon last August, I experienced severe water ingress from around the joint between the awning bead and the awning channel. This was due to the bead being much thinner than the channel fitted on
my caravan. The rain literally pours in around the back of the bead, down the side of the van and the inside of the awning, filling up the low level blind pockets, which really should have drain holes fitted, an obvious design fault!  I phoned Kampa technical
on two occasions but, despite their promises, they never did get back to me. Reading lots about these awnings needing time to "bed in", coupled with the dry weather we were now experiencing, I decided not to follow up on my query - a big mistake I fear.

During my holiday earlier this month, again over 2 weeks in Devon, I have had the same problem again and Ryan, at Norwich Camping, suggested that Kampa are introducing a filler piece next January for Eriba caravans with similar problems and, because Hymer
also manufacture Eriba caravans, I suspect that they share the same size awning channel. 

Ryan gave me a contact at Kampa who would know about this but, despite two phones calls, plus an email, Myles refuses to discuss my problem - not exactly what I'd expect from a reputable company! However, I did manage to get the receptionist, Holly, to speak
to me and although she did acknowledge that I have a problem she suggested that as the Kampa awning does fit most caravans very well it is down to the type of caravan I have and basically that’s my “tough luck”! I explained that I was willing to trial the
new accessory Ryan had told me about on my Hymer this year and I also explained that I would like to know whether the new “fix” would actually work, rather than wait and buy it next year, but I got nowhere.

I'm convinced that my problem is down to the awning bead being far too small in section for the track fitted on may caravan, but does anyone have any experience of this please? Thanks very much for any help and apologies for rambling on for so long.

BTW, the Hymer track is a twin channel, the gap on the outer one which I use measures 5mm and the inner one is 6.5mm.

Cheers,

Paul.
