The USMC combat tent made by eureka fits your needs. Was out on the Tigris building a bridge with the USMC bridge builders. Insurgents had destroyed one of the main supply route bridges. USMC were placing the modulars, we were doing the concrete work. The tank support providing security, slept in the tank. Us Army engineers slept under our fking ponchos. USMC set up their tents.

Three pole design, bathtub floor, vestibules front and rear.
All interior mesh can be zipped up. All three poles are the same size, so makes set up lightening fast.

You could buy six of these used, for the price of that hillberg.

I use Eurekas larger Assualt outfitter 4 based off this same tent. Modified to take a titanium woodstove I've slept in 40-50 below weather. In spring/summer/fall: thousands of miles of river.
