I like simple, but I also like safe.
These days, the best option you are going to find in terms of what you have been talking about is most likely a toyota tacoma regular cab truck.
I think 2014 was the last year they made these. Too bad.
I paid 20 k brand new off the lot in 2012. Single cab, bench seat, five speed, 4x4 manual locks, and windows, two speed wipers and a simple radio/cd player. It has the 2.7 4 banger that has been around forever it is simple, reliable, and powerful. Sure not gonna win any races but short of towing a big *** RV, there is nothing this truck cant do.
Oh.... it has AC.
Yes, there is traction control and ABS, and airbags all around but I am OK with that. It is a small, tough, cheap, 4x4 truck that can go 95 percent of the places we see on this forum if you swap on a set of good tires.
My truck gets 19-21 MPG mixed driving in the winter, 22-24 MPG mixed driving in the summer, and 15 MPG towing 3 thousand pounds. In the summer it hauls fire wood up and down and out of the mountains of back country idaho, carries half a yard of dirt at a time for the garden, and can fit plenty of tools lumber and camping gear in the back as needed. It sees hundreds if not thousands of miles of dirt road ever summer taking me on many adventures. In the Winter time with studded tires and chains there is not a road that has stopped me yet. It pulls my Artic Cat likes its not even there on a little 4 by 8 flat bed, and provides a snug covered bed to sleep in for those early morning, or late evening at the ski mountain. Ever once and a while it pulls three sleds when buddies and I go out together.
So. In my mind, this truck is simple, it is safe, and it is cheap. It tows what I need, hauls plenty, and gets good MPG doing it.
The only thing I have had to fix in the 120 K miles I have driven it ? Serpinetine belt around 100K.
( Update) I Just got a whole new suspension the other day.... opps. But I beat that stock suspension into the ground and the only thing that suffered was my teeth rattling out.
