Hi I am presently at the stage of looking to purchase my first (used) Motorhome. A few days ago i put a thread on the "Beginner" Forum, but having seen this specific forum i feel this may be a more suitable place for my questions. Dethleffs is a brand i am considering and would appreciate the input of anyone who has experience of this type of van (good or bad). More specifically i am considering a Fortero 5975 on a Ford Transit, which is a sub 6m van with a fixed rear bed. This appears similar to a number of other models such as the globevan and summer edition, although apart from the Fortero being slightly wider i can not see any real difference!? I am also aware that Dethleffs use an Alluminium skin on thier coachbuilts whereas others are GRP. What are the advantages/disadvantages of these different types of construction. Thanks for your time.
