the gas tank conversion is pretty easy i have done it twice. i doubt it's any safer but my wife doesn't like the smell or even the thought she can smell gas. so i like keeping her happy so both mine are outside under the bed. cost was around $250 or so.
again i am prob in the minority here but i don't think power steering or power brakes are that much safer. people think they need them because they are used to driving 70mph down the road or faster and following close because their car only weighs 3000lbs. your truck will prob have a crusing speed of around 50mph and as long as you drive accordingly i would take the stock components over some overseas kit or junkyard conversian any day. not saying doing so is wrong, buy i haven't had trouble stopping at all. when an animal runs out or when a light changes it ok. if you are going to try to drive the truck like most other cars and gas brake, gas brake, or speed up to the stop light, or talk on the cell phone while you are diggin on the radio sure change it over you will be safer.
sorry not to get off subject. the worst part of the gas tank under bed is figuring out where to put filler neck and cap. will take cutting and some work and any place has some drawbacks. also you may want to weld up the old hole in the cab and repaint it. good luck i hope you find a truck.
