To drive or not to drive - That is the question?

I have a 42ft with a tag and we pull a 25 ft box trailer and if I get tired or don't feel well my 66 yo wife will drive and ill sleep in the passenger seat. I must say she drives only on interstate and not on city streets. the trailer makes it a tad trickey. and you are going to buy a 42-45ft pusher. that coach will be so easy to drive it will surprise both of you see ya on the hyway
