You will be rewarded if you can just remain calm and keep looking. A few years after purchasing my '77 31' off ebay, I was looking for something shorter, say in the 25' range. I saw an '80 Excella II 25' mid twin/rear bath go for a little over $10,000. I then waited for over 6 months while trying to get a look at a one owner '79 Sovereign
25' mid twin/rear bath in immaculate condition when a couple would visit relatives near by. When I heard they might be interested in selling so they could get a longer trailer, I let their relatives know quickly that I was interested in a shot at their trailer. OK, I figured I would pay a little more but it would have been worth it. I was heartbroken to learn they traded it in on another Airstream while at home in Florida.
OK, the story gets better though. I ran across a post on another forum noting a nice '86 Sovereign
25' with rear corner bed for sale WITH Hensley hitch. I talked to the person who had seen the trailer (I trusted her), sent emails to the owner and then called him the next day. He emailed me pictures and I went straight to the bank to get a loan to tide me over until the 31' sold. That loan is almost paid off and I ended up with a trailer I feel I can take anywhere. It is a little more suited for what I do whether we are talking hunting or just traveling. Settle for only the trailer you want and you will have one you will cherish for years.
