Hi there, I'm Fiona, I'm new to the forum! We're just embarking on our search for the perfect eriba and would appreciate any help/advice. We have two children - 3 and 5. Our IDEAL would be a Triton 430 with bunk beds, however I'm coming to realise that this is very rare!!! The 418 is no good as we need a washroom. The 550 is getting a bit too big we think. Has anyone managed to regularly sleep four in one of the smaller vans? Can a bunk bed be retrofitted? I'm looking forward to the eriba folk wisdom!! Thanks in advance everyone!
