Unleaded vs. Premium gas, does it make a differnce?
My father inlaw suggested I run Premium gas when towing the TT. Makes sense but not sure it makes a difference, any thoughts?

Only place I notice any difference in the MH with running premium fuel os the pocketbook. Don't think the 1999 computer is smart enough to adjust the timing.
The 1999 engine computer is entirely smart enough to adjust the spark timing; that's a pretty basic function of any engine computer unit, and can be accomplished satisfactorily without needing a lot of computer power. The first computer controlled ignition systems were introduced in the 1970s, and by the mid to late 1980s were pretty much ubiquitous. (There were some non-digital-computer-controlled electronic ignition systems in the mix for awhile, too.)
