I have done sewing while camping in our RV. I found I could put cutting mat & rulers behind the sofa. Sewing machine under the table (so easy to pull out when ready). There is more space for things like a small ironing board in the 'lift up' under the bed.
Seems though I read on some forum of caution of electric surges for computerized machines was something to be aware of. I like the idea mentioned here cutting out before you travel.
