I have had the narrow Indespension manual for many years and built a few trailers, using their parts and based on the plans in the book.
The new A4 sized ... book has a lot more information ........ bought it and dumped the old book.
However just noticed today that the section on Trailer plans is not in the new book ......... Indespension confirm they have 'discontinued' providing the plans.
About now I feel stupid for throwing away old manual ....
Does nay one have the old manual, and feel like scanning the plans section and putting them somewhere for download ?
