Not sure whether this is the right section for my request. However here goes. A friend of mine has a 2 year old low milage long wheelbase twin axle Transit van in good condition. He has asked me if I know of any firm who offer a design service for suggested layouts for converting to a motor home. Also where could he purchase the necessary bits and pieces. He is a carpenter by trade and intends to do the work himself and have the gas and electricity installed by competant qualified tradesmen. Any help would be very much appreciated.
