I called my long road trip my walk about. did not do it in a 4runner though, did it in a 2nd gen dodge diesel. I would like to do it again sometime soon.
Lately my road trips are all in Baja, just love it down there. Here is my last adventure rig
I have made several Newport to Cabo San Lucas trips towing my 19' Boston Whaler Outrage, pretty scary trip back in the 80s. You literally pass I bet at least 1000+ white crosses on the roadside which is rather unnerving at night because they didn't have any reflectors or anything for turns, just White Crosses of people that died there. It is pretty effective to get you to slow down and watch the road.
Few Pemex stations but I carried 36 gallons of extra fuel in my portable bladder tanks I used for my boat.
That was done in a 1985 Ford Bronco II of all things.
Never let me down though, even surf launching in the sand.
I think it was pretty well spent when I sold it with just over 100,000 miles though, I took good care of it, regular oil changes etc but I put a lot of really hard miles on it and it wasn't a Toyota.
My favorite Newport to Cabo then to Mazatlan trip was actually in a converted TransPac sailboat that some rich doctor friend wanted sailed down to Mazatlan so he could fly down and use it there. Was about 1000 miles of sailing, fantastic fishing along the way.
We also stopped at a little fishing village off of Cedros Island, we just anchored the boat far offshore because it drew over 16 feet at the keel so couldn't get very close hardly anywhere that didn't have a deep bay.
Then about 20 minutes later this guy comes buzzing out to us in his panga boat with 2 milk crates full of nice lobsters.
We bought them all for a $20 bill a Playboy Mag and 2 packs of cigarettes which we brought with us just for this occasion.
So for a few nights we had fresh lobster and fresh yellowtail and mahi-mahi that we had caught daily.
We also stopped at Magdalena Bay got into the skiff and headed into the bay as the California Gray Whales were stopping there migrating, there were lots of them in this shallow bay which they use as a nursery.
They will actually come right up the skiff so that you can touch them.
I heard now that about 10 years ago they actually started making whale trips to Magdalena bay just for this, glad we got to do it decades before it became commercialized.
I have some old pictures of that trip somewhere I might pull them out and just take digital pictures of them and see if I can post them.
That was my favorite trip.
