It takes a special kind of woman to appreciate all the finer qualities of a deuce. If she's the romantic, candle light dinner, walk in the moonlight, lay out under the stars kind of woman, then use the deuce to do all of those things with her.
Rig the bed with a table that converts into a camp bed; a pair of chairs; a large air mattress; a blanket; a nice, fine table clothe; a nice, quiet generator, the kind you can barely hear over the silence of the night; an electric warmer; a cooler stocked with ice; and a nice, romantic lamp, like a floor stander.
Cook for her (or hire out the catering for) a nice, romantic dinner, at least three courses, and put them in the cooler and warmer. Take her out to a nice, romantic spot in the Deuce, and before her eyes, rig the bed for the dinner under the stars and moon light. Afterwords, quickly clean up and go for a walk. On returning to the Deuce, rig it quickly for laying out under the stars in the bed with the air mattress. Oh, and of course talk some more.
If you're not into talking with your SO, learn.
This will show her all the benefits that can be had from owning a Deuce, and maybe she'll let you keep it.
Might want to bring along hearing protection for her. You don't want her to claim deafness when you're talking.
