You are in very good company by deciding to buy a rig at this time. Actually, by being forced to buy a used rig, you've probably saved yourself a lot of money. (More money for camping trips.)
Very nice modifications and people will probably assume that the stain was meant as a contrast. You've made the changes you needed for your family and that's all that matters.
For dinners, do you eat on the sofa or outside? We didn't find the booth in our tt comfortable or practical, but a sofa and a portable table or tv works.
Congratulations on your purchase and modifications.
