Short bed or long bed?

Years ago I had an extended cab with a long bed when we first started towing our FW. Didn't have a slider and didn't need it. However, when we traded out of that truck, we got a crew cab with a short bed and it actually was not as long as the extended cab with a long bed. The first two crew cabs with short beds I had did have small, 26 gallon, tanks, but the last three, two GMCs and one Ram have all had 34-36 gallon tanks so I think all of them now have larger fuel tanks to accommodate those of us who don't like to fill up very often. When we bought our first short-bed truck, we put a Reese manual slider on it and have used it a few times and it's not really much of a pain, just takes a little more time, but what's the hurry in putting your FW up, one or two minutes sure as heck isn't a big deal. Also, with most of the newer FWs, their front ends are manufactured so that they will generally not make contact with your cab under normal circumstances. As far as hauling is concerned, when I had the long bed truck, I didn't haul anything in it that I don't haul in my short bed, but then, the extra thing I take along with a Crestliner SuperHawk 1900 and it wouldn't fit in the bed of a long bed anyway. Having said that, I would suggest you get any length bed you wish, it's your truck and you need what you want, not what the rest of us think you should need.
