Ironman 4x4 Ursa 1300 vs RoofBunk Adventurer

The Ironman 4x4 Ursa 1300 and the RoofBunk Adventurer are both hardshell tents in the same part of the market, which makes them a genuine head-to-head rather than a comparison across categories. Ironman 4x4 and RoofBunk take noticeably different approaches to the same problem.

Floor area is close to identical at 3.28 m² and 3.05 m², so neither wins on sleeping room. List prices are within $96 of each other, so price is unlikely to decide this one. Ironman 4x4 also backs the Ursa 1300 for 3 years against 2.

They open differently: the Ursa 1300 is a fold-out and the Adventurer a clamshell. That is not cosmetic — it decides whether headroom is even across the tent or tapers towards one end, and how much of the roof the tent occupies when closed. The Ursa 1300 uses ABS hardshell with aluminium honeycomb base; the Adventurer uses powder-coated aluminium. Canvas differs too: 420D polyester Oxford fly; 320gsm ripstop nylon mesh against 320gsm poly-cotton blend ripstop canvas body; 600D Oxford polyester rainfly. Closed, the Adventurer sits 11 cm lower on the roof — 21 cm against 32 cm — which is drag you carry on every mile you are not camping.

Ironman 4x4

Ursa 1300

The Ursa 1300 is the smaller of Ironman 4x4's two Ursa hardshell fold-out tents, sized for CUVs, SUVs, wagons and most truck beds. It sleeps two adults and a child on a 2.4-inch high-density foam mattress and deploys via two base latches and assisted gas struts, expanding sideways from a 65 x 48.8 inch packed footprint to a 63 x 80.6 inch open floor. Integrated star-gazing sky windows, LED strip lighting and a heater/AC hose inlet are included.

  • Two-latch, gas-strut fold-out deployment the maker rates at under 5 minutes
  • Integrated star-gazing sky windows and LED strip lighting
  • Heater/AC hose inlet for cold-weather diesel-heater use
  • Manufacturer publishes the 160 lb weight in imperial only, with no metric figure
