The vertical sidewalks make an immense difference in the spaciousness of the tent. We also have an older 3 person marmot 4 season tent that has served us well over 10 years of travel around the world and wanted something lighter and more spacious. The limelight perfectly fits the bill. Only concern would be plastic fittings and clips for affixing tents to poles over time with extended exposure to sun and temp cycles.
