We have been full-timing now for 3 and 1/2 years. My husband does grumble once in a while because I have taken over the dinette table. I actually have two machines with me, thank goodness as my FW is incapacitated at the moment. I have one good sized cupboard and some under the bed storage for fabric etc. The machine I am not using lives under the dinette table. As with most RVers, we do not have a lot of company. We have some storage at home so I do have some fabric there but we are in Quartzsite, Arizona for 5 months each winter. There are quilting groups in some of the RV parks and in several churches. You say you work camp. Is there a clubhouse or dining room that you could use in the off hours. Just yesterday I sandwiched my quilt with the group I sew with. Much easier than trying to do it in the RV. Our RV is 36 ' long. One of the biggest things is to be organized, have limited projects and fabric!!!!!
I have a limited number of rulers and tools with me - nothing like some of the pictures of sewing rooms I have seen. My ironing board is an old cutting board 9" x 13" with a towel on top which I set on the bar. I cut and sew on the dinette table. It is doable and lots of fun, you gotta find a way, you can't not quilt!!!
