My favorite car camping tent is the Eureka Equinox 2/3 that I have had for the last 10 years. Bought it at the Eureka plant in NY for $40 and it has never let me down. Made a vesibule for it, new poly floor sheet, gear hammocks, the works.... I've used in in winter in 3+ feet of snow with additional 2 feet of snowfall in a weekend, 90+ degree days, strong winds, heavy heavy downpur and steady rain. Only thing is to bring additional stakes to stake out the floor when it really starts coming down.
Eureka makes some awesome stuff at a great price!
