Yes-- not only setting up a tent in the rain, but then having to pack up a wet tent the next day and set it up still wet at the next campsite.
Packing up a wet pop-up trailer-in-a-box seems like a similar problem. Also, we often camp in bear country, so having a hard-sided camper was a must for us. From that decision, an Airstream was the only one we really liked. A lot.
On additional thought for tenters, is that having an RV greatly expanded our options for places to stay on long road trips, namely in RV parks. Some RV parks accept tenters, but some don't. There seem to be a lot more RV parks than tent-friendly nature-based parks along the highways.
