Congrats on the basecamp purchase. I got mine from Dean back in March (or was it February?). Anyway, the family loves it and we have had no regrets and no problems. I have made the "standard" changes that other Expo members have pointed out are worth looking at and inspecting (#8 bolts, wiring harness, safety chain, bearings, etc....). one thing us "base campers" have going for us is the second tent (the one which deploys under the top tent when the rack is opened. I have found that due to the way it attaches and hangs, the shape and thus ease of entry was a little frustrating, even when staked down. I took some spare tent shock-cord poles (not from the Conqueror but an old 4-person nylon Coleman model) and use them to [blossom] out the lower tent. I use three poles, three sections long (if that makes sense); one assembled pole at each end and one in the center, bent in an arch and installed on the inside, to create a nicely shaped additional sleeping area. (I'll try to find a photo to post)
The roof rack has been great for bringing along a collapsable awning among other things (the rack makes a great bike rack!) which we use over the kitchen area if we don't set up the large awning (which in truth I've only used once).
Having the two 10lb propane tanks has completed the look, but I am still finishing off a 6-pak of disposable bottles I purchased when we first bought the basecamp. After two trips with just a cooler, we sprung for an Edgestar 63q freezer and its been great.
We use a blow up mattress up top for sleeping and I purchased two folding cots (an XL model) from Cabelas. I took 6" off each end of the cot (not only were they wider than standard, but also longer) - as in a foot too long to fit cleanly in the lower tent. As the cot frames are aluminum, it was an easy adjustment. So now there's a sleeping and "hang-out" for the kids. One other thing, I went with a cot that didn't have individual "legs" but more of a short U-shaped support to hold up the sleeping surface. I didn't want a legged-type model for fear of tearing or ripping through the bottom of the tent. I always use a ground cover under the Conqueror lower tent and haven't had any problem with moisture wicking or morning dew seaping in. (Yeah, one of the things I did after seasoning the canvas was to wax up all the seams on both tents. Lessons learned long ago after many years of tent camping as a child.)
Lastly, I was able to register here in Texas at 1750 lbs empty.
Hope you have many years of enjoyment with this unique trailer.
