I'm a little sensitive to this issue, so I apologize in advance, but here is a brief analysis I drafted up on another forum:

If your motivation in moving the tank is because of safety I think you are wasting your time.
It sounds like you may have done some reading, and so you may have already seen this thread, but I would ask you to read it again:

My editorial comments are documented there, although perhaps not as eloquently as I would have liked.
Secondly, your comments re-piqued my curiosity about this topic, so I did some (hopefully detatched and unemotional) research:
I wondered
"...how many deaths were there, really, as a result of this?". So I did a quick internet search.
The National Highway Traffic Safety Administration (NHTSA) has documented what they believe to be 1800 fire related fatalities in '73 - '91 C/K and R/V trucks, from 1973 through calendar year 2000.
First off, in looking at the data, from what I can tell they don't distinguish between pickup, Blazer and Suburban - the later two which would not have side saddle type tanks - so the actual number will be somewhat smaller than the 1800.
Secondly, if you read through the data, it does not distinguish between "fire" as the cause of death vs "fire as a result of side saddle tanks" as a cause of death. Many of the fatalities occurred as a result of single vehicle accidents where the truck struck a tree or a pole or a bridge abutment. One could assume that in those cases the vehicle was moving forward, likely longitudinally (and perhaps at a moderately high rate of speed), and the fact that the tank was mounted on the side of the vehicle would be moot. (That is, these were not situations where the victim vehicle was T boned in the side - specifically the side that the tank was on - resulting in fire). This would also reduce NHTSA's number of fatalities directly attributable to side saddle tanks.
Lastly, in reviewing their data, in some cases there were two, three or even four people involved some of the vehicle incidents. So - the number of vehicles impacted (ie, specific crash events) was something less than 1800, like 1200 or so.
However, for the purposes of this discussion, let's do some math and use their number of 1800:
NHTSA estimates there were roughly 10 million of these vehicles produced (Note: I think that's low, 15 plus model years many of which were more than 1 million per year - but again we'll use their number). If we assume each of those vehicles traveled 50,000 miles in their lifetime (again, I am choosing a low number on purpose, as mine has nearly 200,000 miles) then the number of miles traveled in these types of vehicles would be 500,000,000,000 - hopefully that's 5 with 11 zeros behind it, or
500 billion miles.
I am relating it to miles traveled because that's the factor that causes you to be "exposed" to something bad happening. Said differently, there's really no danger when the vehicle is just sitting in the driveway. 500 billion miles - that's a lot of "exposure".
Your odds of dying in a fiery death, then, according to NHTSA would be that number divided by 1800 or 1 in 277,000,000.
One in 277 million.
Just to give this number some perspective, I did a quick check on some other comparable statistics: your odds of winning the lottery, according to one website, are one in 120 million. Your odds of being killed on a commercial airline flight are one in 19 million. Your odds of being struck by lightning, the standard of measure in this type of thing, are one in 750,000. If you prefer a "straight up" numbers-to-numbers comparison, I found that there are roughly 12,000 deaths attributed to "slip and fall" incidents each year.
So basically you are twice as likely to win the lottery, 14 times more likely to die in a plane crash and 370 times more likely to be hit by lightning than to be killed in one of these trucks as a result of fire, according to data from the National Highway Traffic Safety Administration.
