First review the current new popup campers and decide which ones should be on your list. Then add the tie-downs and wiring adapter to your truck so you can quickly go and buy a camper and take it home with you on a single trip.
Start looking for a used one on craigslist.com (and searchtempest) and the RV classifieds sites and have the cash ready. There are far fewer popups and if there is one available that is in very good condition it is not going to be around for very long.
Popups are a lot more popular in the southwest for trail running but you may be able to find something within 300 miles of where you live.
