I bought an aircon unit for the van but the exhaust section couldn't be used because of the way the van windows are set up. Called into mcdonald & lappin of 5 Silverwood Industrial Park, Lurgan. BT66 38325132 with a scrappy sketch of what I would need to rectify the problem. Got a call four hours later to say new brackets were ready. Fit perfectly, and very reasonably priced. Worth noting motorhomers, if you can't weld or any of that stuff.
