We have a 32' MH & like to travel with our 4 cats. It's just us and the cats (no kids). I cannot leave home without sewing projects. What worked for me is taking my projects precut and ready to sew. It's amazing how fast you can get them sewn together. I also have the revisble cutting/ironing mat and a good Black & Decker travel iron and Ott lights. I sew on the dinning room table. We like to be gone for about six weeks at a time and we usually stay in one place no longer than 4 days depending upon what is there to see or do. The first trip was out West and I took my Bernina 730 which was stored in the shower along with my fabrics, etc while we traveled-----until my husband forgot to empty the gray water tank and it backed up into the shower. Luckily my 730 was sitting next to the bed and no damage was done. After that I started taking my featherweight which I could easily store under the dining room table. My 730 stays safe at home. The shower is normally great storage space when you are on the move. You will probably have more living space in your trailer than a MH. Have fun.
