2017 Travato 59K Seat Covers Floor Mats, Locking Gas Cap?

[LucyLucy]

Hi,
I have a 2017 Winnebago Travato 59K.

Questions:

Does anyone have a resource for seat covers for the driver and passenger side?

Weathertech does not make mats for the Travato (they have a material you can purchase that you can cut to size). Does anyone have a resource for mats for the driver/passenger area?

Anyone have a resource for locking gas caps?

How difficult is it to take off the sliding screen door? Don't want to open up a can of worms!

Thanks to all of you experts!
