Widest tire you can run in the rear?

A 20x15 will only have limited tire selection (Mickey T Sportsman S/R Radials) so that's basically a pro-street radial & not really touring. Michelin makes a wide sticky Z-speed rated touring tire but I would guess the wheel width is usually the 12.5-13" width.

Mickey T's 18" wide version fits the 15" wheel & has 29" & 31" height options. That wide of a combo fitting between the outer bedside skin & OE rail placement will depend on how low it sits. The better option is a 20x12 or 13" wide. They'll have room to spare after modifying the tubs.
