We have a Forest River Shamrock 21ss and it's surprising how much heat it actually retains given the tent ends. We use the heated mattresses and I keep a 1500 watt electric heater handy if it gets too cold and we have powered site. Otherwise the furnace works fine :)
Performance Improvement Opportunities?
I have a great travel trailer and I rarely use it. So I started thinking about what real and imagined issues keep me from using it more than I do.
Batteries! My batteries drain too fast and need replacing too often. Not an issue at campgrounds with electric hook up.
Refrigeration. My refrigerator is all or nothing and keeps food frozen more than cold. I play door games with it, leaving the door cracked at night so it doesn't freeze everything and leaving it closed during the day.
Local camping options seem silly when I could be hitting these places for day use and enjoying the comforts of home at night. Distant camping options require advanced planning, a luxury I don't have right now (Come on retirement, come on!).
The rest of my issues are towing expenses, maintenance, repairs (not a do it yourselfer).
Meanwhile the trailer sits there. I want to affordably start getting my money's worth out of that trailer! Not really to get my money's worth, but to enjoy camping with it, because I do enjoy my trailer once I get it somewhere and get it set up.
Well, those are the things that effect my frequency of use. What are yours?
If you're worried about the comforts of home, you're not a camper...sell it and move on :)
I've got a 2009 21ss, no problems with seals or bed ends yet, although It does have some slight delamination at the bottom of the front bunk door. Couple years ago I caulked around the metal framing on the front door/fibreglass and it stopped the delam. First thing I would do on a new hybrid is caulk around the doors.
On another note, you can buy the door insert as a unit from forest river. Should be an easy fix if you are even a bit handy.
