After seeing many wet room woes. I would recommend a shallow tray instead of a wetroom, easier to install clean, less to go wrong and easier to drain. they do black and grey ones now.
Running a 2002 3.0 auto. Would recommend. Now done over 210k miles. Keep it under 55mph and mpg is very good for the size. Great acceleration, cornering not so good but a great cruiser.
We host via air bnb and sometimes there is a problem in sending emails and messages as airbnb tries to block emails with web addresses, email addresses and attachments. Also some people only check emails etc twice a week.
You should have had a contact phone number – have you tried calling the number?
