I really am considering a popup myself. I had one before but discovered after I purchased it that I had missed water damage and got rid of it at a loss. But.....it was very roomy inside with the slide out end beds extended. It was pretty easy to set up, and had ac, heat, sink, fridge, etc. I liked the convenience of towing something very low profile, and could hardly tell it was there on the road. I was using my 2014 Ford Escape csuv.
I am sure that it would be kinda noisy in big wind storms, but how often will that happen? And if it is supposed to be very strong winds you can always put the top down and stay in the car for the night. A little inconvenient sometimes but maybe worth while for the roominess and amenities they provide as opposed to other things. They are nice to stretch out in, cook, sit at a normal size table, sink, storage drawers etc.
What I also loved about it was it had screens all the way around. Popups are very airy with all the windows open and comfortable (plenty of ventilation and fresh air). You could even set up a shower facility inside and porta-pottie.
So I am very much considering springing for a $1500 to $2000 used popup again. Of course this time I will check them out with a fine tooth comb. I have learned pretty much about them since I was taken the last time.
As far as the Aliners are concerned, I am finding that they are lots more expensive than the regular canvas pups, much heavier, and have less inside space.
So, if I go back down the popup route again and test it out around here in Florida and maybe a little further out, I may just head on out to the winter RTR to give it the desert test as well. I mean.....what's the worst that can happen? If it gets too windy I will drop the top on the pup and ride it out till things calm down in the Escape. In other words escape to the Escape!!! I lived out of it (Escape) for a month and survived, so a day here or there every once in awhile won't be bad.
Maybe if they catch on and they are a pretty good living arrangement Bob can set up a special popup category under Choosing the Right Vehicle. Well........maybe not.
