How much gas am I looking at for a couple hundred mile trip?
Thanks for advice.

too many variables to estimate. slight differences in timing or ignition system condition could lose you a couple mpg easy. Tire condition, size and inflation and driving style, aerodynamics of your specific truck, final drive ratio, etc. BUT, a huge ballpark would be 8-12. All you can do is fill up, bring a gas can, and drive until you either run out or make it halfway. Then fill up again and you''l know how far you can go. The calculations listed above (Veinbar) are the best way I know to figure it out.
However, do we know for sure if your odometer works without the speedometer working? I don't think it does on an older vehicle iirc the odometer is driven by the speedo cable. BTW, speedometers aren't hard or expensive to fix. I would do that and a tune up before any trip, if I was worried about it. Good luck
