they are called folding trailers on there....

Lowest I see right now is $1,395
You can ussually find one with out air for $500.

My opinion on Pop Ups, we borrowed one and we stayed a week in it a couple years ago while selling fireworks out of state. It was only marginally better than a tent with alot more hassel. I personally will never buy one unless it's uber cheap and I can turn a quick dime on it, but not to use. 2 grown ups + 2 kids... crowded does not describe it. 1 grown up trying to cook while everyone else is not in..... again crowded is not a strong enough word to describe it. Sleeping it was comfortable, but so is an air mattress in a well placed and secured tent. Pluss my tent has more room, and weighs a whole lot less.
When it's folded down, you have some room for storage, but not enough... You still end up with the bed and cab full of gear to get where you are going. Then you have to set up and unload it all and put it in it's place i nteh camper. Then tear down is same in reverse. PIA!!!!
With a Travel Trailer (aka TT), you keep your gear in it and just grab a few things, clothes, food, etc when your ready to go and throw them in it. then take off. So little to no packing involved..... Set up is parking it and hooking up to facitlities.... Heading home is securing objects, unhooking facilities, hooking up to vehicle and leave... get home take out clothes and food and you can relax.

We are keeping an eye open for our first TT now.

 

They are 110....

Yes, you can plug them into a house or even a small generator with an extension cord you need one of these.....

For cord on the camper......



other side of the addapter is standard 120v plug....



I think I picked mine up at walmart or lowes for like $10.....

Before we took off in the pop up we borrowed it had been sitting for a couple years and had mildew and molded, we had it set up in the front yard hooked up to an extenion cord on a 20 amp GFI outlet for a week prior. Cleaning it wit hMean Green every night.....However it did not have A/C. So was only running lights with it.

Also many of the new units are bi power, propane/electric......
So the ac and refidgerator will run off teh propane tanks. This is nice, you can turn the fridge on the night before and keep it on till you get to teh camp site and get it plugged in. You can turn teh AC on before you leave and it will be cool when you get there. It takes a few hours to get a refridgerator cold, so then your not putting your food in a hot fridge.

Edited to add:

The unit will say if it's bi power it should have indicator lights telling you which one it is running on and should switch automatically. So check to make sure that it works on both.
To run on electric just plug in the camper... it should say electric. Then while it's running unhook the cmpaer and it should switch to propane and tell you it is on propane power.....

Also some are tri powered...... 110AC, 12v DC or Propane..... if it has this then again cheack to make sure it runs on all 3 power sources....

 

We had a pop up for a couple of years and it served us well, but we were more than happy when we got our TT. The hassles we had were similar. Biggest beefs we had were you either had to pop it up to pack it with food, clothes, sleeping bags, etc. and even then you wouldn't be able to fit everything and still close it. Or we would pack everything in the back of the truck and then unpack the truck to pack the trailer when you got to the destination. It made quick one night trips more of a hassle than they could've been although we had a pretty good routine going.

On the other hand, they are light and easy to tow. We got it before we got the truck and I didn't even know it was back there when I was pulling with the truck. We liked it a lot at the time but you might also look at a small TT too say 17ft-21ft.

You might check out the message boards at Popupexplorer for more information on yrs/models/prices, etc.

 

PSS Mag, your experince sounds exactly like ours! Nice now to just put food in and go. We have a complete wardrobe that stays in 5vr. Just add heavy coats in winter, food, hookup and go.

Another little bit of advice on the fridge, you can turn them on in advance to get them cold inside, but if you go buy a bunch of jars of condiments and beer that are not already cold, it will take forever for the small fridge to get cold. Hint here is to buy your items a day or 2 in advance and put them in your home fridge to get them cold....
