The dealer's Service department has been the big blocker on the delivery, they just haven't got enough technicians, but I got the last laugh.
As I understand it, another customer had ordered a similar MH to mine and had chosent to add a cat1 alarm on it (£650)
and this work meant that his vehicle had to be taken to that manufacturers site to have it fitted - the rush to get out as many customers ordered vehicles for Easter was on and in this 'chaos' the workshop took my vehicle instead of the correct one and the error was not noticed until the alarm-fitted vehicle was returned to the dealer - oops! I now have a top quality alarm fitted at a total cost to me of zilch
and the other customer is still waiting for his vehicle to be delivered back.
