I first measured the shelf in my truck so I knew how much room I had to work with. The HP OfficeJet I already owned wouldn't fit. So I went to the local office supply store and measured the MFD's (multi function device) in my price range. If it's for office work I recommend one that copy, scans, and prints. Also it should be able to scan and save to a .pdf file. Some low end MFD's will only save to .tiff or some other picture format rather than .pdf. Also I recommend one that can save to some sort of removable memory such as USB or SD card. WiFi is probably a good option too since it gives you another networking option. I ended up buying an Epson WorkForce 645 because it had the features above, the right dimensions, and the right price. I forget the price but it's not the top of the line. I haven't had any problems with it. I had it in my truck since I bought it in February 2012. I think any of the MFD's will be fine in a truck. If you want to feel a little better you can buy an extra warranty at the store you buy it from (if available).
