We just bought a used 99 Wilderness GL 27F and got all the books etc that it came with. The owners manual is not model specific and is very general in nature. What I am looking for is literature from 1999 that talks about the features of the trailer. Was the GL series top or bottom of the Wilderness line for 99? Answers to questions like that are probably in the sales literature for that year.
