We found that sleeping across the trailer was not comfortable, especially when getting up at night and having to crawl over someone. So, we turned the bed configuration. We found it hard to get into the loft, so I added some steps to make entry easier. I added some storage bins for clothing and additional clothes bars for hanging clothes.
Exterior
This trailer did not have air conditioning and we needed it. I found an air conditioner that would fit into the open back window, made a platform to sit it on upon arrival at the camp ground. Cools great. This trailer has hot water, furnace, stove, 3 way fridge (12 volt, propane and 12o v). This trailer also has solar power that keeps the battery charged for boondocking. You don't have to have city electricity. Solar will run water pumps, lights, radio, furnace, etc. (but not the 120 v air conditioner).
Customization
There are 2 new tires on the trailer (just over a year old) and I have 2 new tires and new wheels that have never been on the ground yet.
