I need new canvas on my coleman newport. Can you

Larry, I have checked on this for you and with four companies and each are having issues with locating a replacement. They asked for the motor model number? Do you have this? Please let me know or you can contact them directly Adventure RV Center 2910 Newport Highway Sevierville, TN 37876 Tel. 865-429-3698.
Sorry I could not help more.

Sincerely,
Mike Carvalho

HI Sue.
not sure if this is what you are asking for but try this link out.
how to order new mattress for the Newport hammock Google Search

take the camper to a jayco service center and get the correct replacement items for that camper
then it is a matter of removing all the fitting strips to allow removal of the old canvas and the fitment of the new items
a clue her is to when the new canvas id fitted is to leave the camper opened up and to wet the new canvas with silicon fluid and allow it to dry put before folding it away
why , it stops water coming through the canvas when touched in the rain and prevents mould if folded away when wet

I need this manual too! Anyone have one?

Still looking? I have a original instruction sheet I can send you a copy! [email protected]

You can do this. Another possibility is to have an upholsterer look at it, or even a sailmaker, if you have one close.
