I ran a ground tent for 2 years and switched to an iKamper Skycamp 3.0 on a Prinsu rack last year. Here's my honest comparison after 30+ nights in each:
- Setup time: RTT wins hands down (5 min vs 15 min)
- Sleep quality: RTT is better — built-in mattress and off the ground
- Cost: Ground tent by a mile ($200 vs $4,000)
- Wind: Ground tent is more stable in heavy wind
- Weight/MPG: RTT adds ~120 lbs up high, noticeable on highway
Would I go back? No. The convenience is worth the cost if you camp frequently. But if you're out once a month, a quality ground tent is perfectly fine.
