Good questions Tom.
For starters we need to be clear that the
Australian Winnebago isn't the US Winnebago. They just have the same name. The companies don't have and never have had any relationship. The Australian folks have taken on board developments from the USA and Europe and then allowed for Australian conditions and requirements. On the other hand the
Swagman stable is part of Cummins so it is likely though not a dead set guarantee that it will be similar to US designs. Check their link to see their new MH with a
kevlar body.
Back to the Show, I think the show will have the Winnebago, Jayco and perhaps some other imported European motorhomes as there was last year. I will try to get some info about these for you.
From memory only one 5th wheeler was displayed last year, The Flagstaff by Forest River (modified for Australian Standards),
Dave Benson Vans had it. The word from competitors was that it was the same as was displayed the year before that as nobody ws interested in that mode. See what they show this year. I see that
Forest River Australia have a new 30 footer available. Maybe we will get to see that too.
