I have the same problem when we go south in the winter. Our current 5th wheel does not have a desk so I end up sewing on the kitchen table which makes a complete mess in the trailer. We are going to look for a second trailer to leave south as it is very hard on the trailer to be pulled back and forth from Canada.
In the summer up here I like to sew when we are camping in our add a room and it which works great I can watch birds and sew at the same time. But I find Yuma Ar is windy and the sand gets in everything. Not good for my machine to say the least.
