I've not driven all that far at one time in the TR, longest was probably VTR 2001 in Breckenridge, CO. Roughly 2500 miles total, including sidetrips. But I drove alone (with my daughter in the car), much of it on secondary highways (out past the Grand Canyon, through Durango, CO where we rode the steam train to Silverton & back, etc.)
Let's see, that was the trip where I blew a headlight fuse, coming down the mountain into Durango. I was also having trouble with valve seat recession, which didn't stop the trip but did keep me from trying to compete in the autocross. I remember driving up to I-70 to pick up a coil wire, but as I recall it was mostly an excuse to go driving through the mountains.
I've done several other trips around 2000-2500 miles. All had some minor troubles, never enough to require a tow truck. Couple years ago, I drove the TR3 to Tucson to join Geo and others for the "Arizona Roadrunner". Probably drove 2500 miles with most of it by myself through the desert. The block drain started leaking, so I stopped and wrapped a hose clamp around it. The front end was vibrating kind of badly at freeway speeds, so I came home early (still haven't fully resolved the vibration problem).
Longest in the Stag would be VTR 2005 in Rockford, IL; about 6000 miles total (went to visit family in IN afterwards). Again drove alone (solo going, daughter rode back with me). While packing to leave, I inadvertantly left the ignition on, which allowed the leaking float valve to fill a cylinder and hydrolock the motor. I was running behind (took longer to put the dash back together than I had allowed), and was very tired (hence the gaffe) so I just let it sit overnight and went on.
During a big rainstorm near Denver, I plowed into a bunch of standing water, which came up over the hood and broke the driver's side wiper arm. (Early Stags had a plastic pivot piece that was kind of fragile.) So I tie-wrapped the arm (leaving it working but without the pantograph function). The front tires wore out, so I stopped somewhere in Iowa for a new pair of tires. Then on the way home, one of the head gaskets started leaking and the alternator came loose. Wasn't too far from home by then (and it was around 4 AM), so I topped up the radiator with melted ice from the cooler and limped on home.
I do carry a cellphone & AAA card; but they're not much good when I don't have cell coverage ... :laugh:
