My guess is that this is part of the problem. I would also guess that a 50mm prime at almost any cost point will focus more sharply that the kit zoom.
A 50 mm lens would require you to prefocus at 40 feet at F11 to achieve a near focus limit of 20 feet to infinity. It's not the equipment....user error.

Thanks David.
The OP blames his el cheapo lens not giving distance information.Use human judgement for simple distances. I'm sorry, it's not your equipment it's a failure to understand the implementation of hyperfocal focusing, and setting an autofocus point to the correct distance for near focus and using a DOF application to find your point of infinity.
I gave you what you needed. F11, 30 mm on a Canon crop camera equals focusing approximately 20 feet giving you sharp focus between 10 feet and infinity.

No need to get testy. I am not blaming anything on the equipment. I have offered it as a possibility along with my own personal frailties and short comings. The purpose pf my post is to consider all options. Unfortunately, I cannot go back and reshoot so I am trying to visit all possible solutions for the next time. They have another station with four more engines. lol
You might try back button focus to lock focus on the truck and then re-compose to your liking.
I only read the first, and last page of the thread, but I noticed your camera was mounted on a tripod, and you were using a "IS" lens. Did you remember to turn "IS" off? It could be the searching the "IS" system uses could have blurred the image. Of course I agree a better tripod, adjusted to your eye level would help a lot. Viewing the image, once taken, with a "Hoodman loup" may have helped too. Shooting this photo, in bright light, with IS on, hand held, using spot focus will only allow the camera to focus on a small section of the truck. Since I'm a Canon shooter, but not your model, I would have shot the truck using a wider focus area, like a zone focus. It seems the truck is sitting at a angle, zone focus would take into account a much larger area to focus, and would average out the angle to the truck.

I am pretty sure that I tilted the tripod to place my center focus point on the truck logo using BBF and AI Focus. Then I resettled the tripod to center the image. I would have released the BBF before I moved the tripod back into position.
I am not sure if this would have caused the camera to refocus at that point.
I really appreciate all of the responses but it is beginning to get too much for me to sort out. Hell to get old. lol
Several things have been mentioned that I will try next time.
When I am using my Sony QX-10 on my iPhone there is a touch option for focusing. On the phone screen one can touch the spot where one wants the focus. Do regular cameras have such a feature?

I believe that some do but mine does not. Probably would have kept me out of this predicament. lol
That's fantastic. I hope I'm still going at 88 and what a bonus to be able to enjoy photography too. Not only that but many our age failed to grasp the computer and the electronic age.
Good for you. Thanks for posting.

The other day I took several pictures of the fire trucks used by a local RFD. I gave the shoot a lot pf thought regarding best shutter speed, aperture, ISO, etc. I am fairly new at serious photography and wanted to do it all right. Despite my best efforts I blew it.
Instead of focusing on the truck my spot focus actually focused on the roof edge behind the truck. The good thing is that I was consistent and missed focus on all four trucks. Sigh!
I thought that I had the focus point on the truck. Thinking back over the situation I think my problem may have been parallax. My tri pod does not bring the camera up to eye level so I was bent over, the sun was bright and I probably rushed.
I even tried to use Live View but the sun was much too bright to even see the screen much less use it to focus.
I have considered the hoods and believe that they may help but I know nothing about them.
So what do you do in this situation?

I focus then re-frame. This works well for me in such situations. I do not trust the multiple points that the camera randomly chooses. At times this is good but for this not for me. Get a taller tripod or learn to stoop over to view.
suggest if touch screen use that to be sure its focusing where you touch... or d it all manually.. auto focus should read OUGHTA-FOCUS... be careful.. my canon 50d routinely screws focus like that.
you didnt mention a camera model .. or i missed it. hope this helps..
