Intro. And seeking advice

Have you been camping in a TT before??? have you pulled an RV in the past??? there are other things then floor plan to consider. I'd rent a few models and stay in them for a few days before committing to one if I'd never done it before. Does it have a walk around bed, can I get the job done in the bathroom, can I get to the bathroom with the slide in if it has a slide, can we stop for lunch at a rest stop with out having to put the slide out, etc.
Is there a comfortable place to sit and watch TV for a extended period of time, enough counter space to fix a meal and do the dishes.
