I've found a couple of threads dealing with making the gaucho a bit wider. Since it's just the two of us, and no one sleeping on the dinette, we have no problem extending the bed all the way across the center aisle (blocking the refrigerator door!) at night.
Seems like a futon mattress and a stouter wooden or aluminum frame are favorite solutions.
Are there any A/S specialists in Texas anyone can recommend for such an upgrade?
