Welcome from central Texas and I also am an avid RVer...have spent months at a time in the unit and beginning Oct 1 will be a 6 mo gate keeper at one of the corp parks in our area. The sewing machine and the 3 four legged little guys are always there. Plastic boxes with 3 to 6 compartments are great for stash and notions, sm ironing board behind chair and larger amount of stash in big plastic bins in the basement....where there is a will there is a way and I use my dining table for the machine...a small two drawer file cabinet works well also...happy and safe travels to you....if you end up in Fredricksburg, maybe you can come by and stay at my park...??
Blessings and fun....
