With first things first:
Welcome to the Dieselstop! /ubbthreads/images/graemlins/smile.gif
With a little and patience and learning on your part, you'll find this website an invaluable source of information for your Ford vehicle equipped with an engine built by Navistar/International Harvester. Members here are eager to pass along the knowledge and wisdom they acquire at the Powerstroke School of Hard Knocks! /ubbthreads/images/graemlins/rolleyes.gif
The forums are divided into categories and forums. You have landed into the sole forum dedicated to all things related to Ford Econoline Vans equipped with diesel engines.
At this point, you can help us help you /ubbthreads/images/graemlins/wink.gif by clicking on "my home" in the top yellow bar and updating your signature with some particulars about your vehicle in question. Typically we can know by the year what engine it has, but it doesn't hurt to specify.
Your use of the words "stacks," "cab," and "sleeper," cause me to doubt that you are asking for advice regarding an Econoline. If you'll click on "main index" in the top yellow bar, right next to "my home," you'll see an index of the forums with descriptions. Here are my recommendations for you:
1) visit the "upgrades and aftermarket" forum for whichever engine you have.
2) visit the "upgrades and aftermarket" forum for some of the older engines and body styles, on which you may have noticed a larger population of stacks.
3) visit the "upgrades and aftermarket - general" forum
4) visit the "general diesel" forum.
When you use the search function, try a search for some of your key words in each of these specific forums. To search for posts that contain all three words, you must put into the window "+stacks +cab +sleeper" Omitting the + sign will cause the search to return results based on that word individually.
Good luck.
