Definitely transport them in an upright position. If you take them to a welding supply store to get them filled. They can show you why they need to be upright. Once you see how the valve mechanism works you will understand.
I have always hauled.my 40lb tanks and sometimes a 100 lb tank in my pickup laying down. Never had a problem.
The relief valve needs to be in communication with the vapor space of the cylinder in case it opens. For this reason, all consumer propane cylinders such as this should be stored in an upright position.
Transporting incorrectly and getting away with it doesn't make it safe. Suggesting to do so is wrong.
