Another vote for the popup with small kids. Really makes for a happy wife, the worse the weather is the better the camper. I power the microwave with the inverter in the 100 for 3-minute mac & cheese. This is our current setup... was about $2k used then a couple years later another $2k for the SOA and toyhauler mod.
This was our first camper, back when we just had one kid. Also SOA, but smaller 8' box and it got really small feeling when that pack & play came out again. I miss the tow vehicle more than the camper.
