Partner,
Research, research, research. Just you and your son, something that sleeps 4 comfortably. I am a hefty guy, a twin to be quite frank, is too small if you want to be comfortable, my personal opinion. Make sure your kitchen, and slide are out are over the axles. High ground clearance is great if you plan to camp in rural areas, I don't know the particulars of your F150, but if your planning to change tow vehicles, make sure what you purchase , that vehicle can tow the weight as well. If you live near a factory, go take a tour, see for yourself how its made. Aluminum framing is super strong. Always plan ahead too, you might not be camping in winter climates now, but maybe later you will be, good insulation, heated tanks, a nice feature is a slide that allows you to walk in and walk to the back, slide retracted. Slide awnings are good feature too, sticks and pine cones can damage your slide seals. When we were doing our research, I went into the repair shops and struck up conversations with mechanics, they usually know which models are better than others by what is coming into their shops. Most rv's all use the same brand of appliances, so we looked at the recalls, the worst ones with manufacturer complaints , we stayed away from. Go to an rv ralley, mingle with rv folks and ask, ask, ask. We did that too. Anyway, that's my opinion for whats it worth.
