Hi,
the best place to get information specifically for Jayco Camper Trailers is the Jayco Camper Trailers Owners Australia Facebook Page:

As far as I know
@Boots in Action and I are the only members on this forum who currently own a Jayco Penguin Camper Trailer.
Replacing the entire canvas walls is not an easy task and is quite expensive. A google will give you a list of canvas people that can do the job that you can contact to get an indication of cost. In the current environment you would be well-advised to also get an indication of when they can do it.
When I initially looked at getting a Penguin, I started chasing a cheapie to avoid wasting money if we didn't like it. But by the time you look at the rubbish that people were selling, factor in the cost of repairs for what you can see, then add some more for fixing things you didn't or couldn't see, they were not worthwhile.
By the time I increased the amount I needed to pay, I wasn't that far off the price of a new one when one considers the discount for buying without a trade and haggling. Then with a new one you get the full warranty and being able to option the van to have exactly what you want.
However, there are now two extra factors to consider: many people selling still think it is a seller's market and are pricing vans accordingly and vans always sell at a premium in the lead up to the summer holidays. Especially when there are massive lead times on getting a new van.
Another factor to consider at the moment is the huge backlog in getting any servicing or repairs done to a van as well as the time it will be idle waiting for a repair regardless if it is in warranty or not.
cheers
Mike
