Outdoor calculator
Rooftop-tent selector
Campers choosing a rooftop tent class. The decision this page isolates is narrow on purpose: translate sleepers and season into a rooftop-tent class. Capacity, season, and packed size are the published facts that survive a weekend trip.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Thule, Yakima, and Smittybilt. It produces an explainable class so Thule Approach M, Yakima SkyRise HD, and SmittyBilt Overland GEN2 Tent STD - SB2583 can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in Thule. This page does not quote a price or rank a brand.
