How do you set up a Subaru Ascent for camping?

  • Folded rows leave a small step at the second row; a thick pad smooths it.
  • Family of five? Row three down, coolers against it, bedding in a roof box.
  • Standard roof rails make a cargo box an easy add.

SUV and tailgate tents for a Subaru Ascent

What should you sleep on in a Subaru Ascent?

Measure the floor with the seats folded before buying anything. A thick self-inflating pad (3 to 4 inches) follows small slopes and steps in the folded seats better than an air mattress, and insulates the cold floor. SUV-specific air mattresses that fill the rear footwell suit people who want the widest bed and do not mind the pump. Either way, add a foam layer when nights drop below about 50F: the car floor is cold.

Frequently asked questions

Can you sleep in a Subaru Ascent?

Yes. Measure your own from the tailgate to the back of the front seats with them slid forward, then pick a pad or mattress about 2 inches shorter. Ventilate with two windows cracked behind mesh screens, and never idle a gas engine for heat while you sleep.

Will a family camping load fit in a Subaru Ascent?

A family-of-four load of a 6-person tent, two coolers, four chairs, bags, pads, stove, table and duffels comes to about 32.2 cu ft packed. Subaru Ascent usable cargo is about 35 cu ft by our estimate, so it fits, with care.

Is it safe to run the engine while sleeping in a Subaru Ascent?

Do not idle a gas or diesel engine for heat or air conditioning while you sleep. Exhaust can leak into the cabin, and snow or a nearby wall can trap it, and carbon monoxide is odourless. Use insulation, a warm bag and a pad for cold, and a battery fan and window screens for heat. Carry a battery carbon monoxide detector either way.
