Consider an Explorer Camper & Canvas Camper Trailer.
They are less that the $25,000 tand come with all the options including choices of Kitchens, Power options and of course Tent options.
We bought a 9" Lawson with annex walls. the canvas is perfect in everyway and the design means that there is no requirement for Guy Ropes.. we went camping last weekend with some friends that have one of the campers mentioned above and we had to step over guy ropes all weekend, not an issue but if we also had guy ropes it would have been like a spiders web... It goes up in no time and packs up the same, one person can easily put it up and down and then with the massive room under the adjustable cover for all your extra stuff.
The other beauty is you buy from the blokes that make the whole thing, trailer is built in Gosford the tent hand sewn by Scott of Explorer Campers and Canvas and all is fitted out by Andrew...
If you don't consider one of these and buy something else you could be doing yourself an injustice, when you do see one in the flesh and you have bought something other you could well be rather P$%%ed off...
They are great ... Another thing that is stand out, The Canvas is designed in a way that it remains taught i.e. no sagging canvas, if you are like me and like things that are built well and look look neat as a pin check these out...
