Roof tents and grizzly rules
A roof tent works well for Montana’s long gravel days, but read the food storage orders before you buy. On the Custer Gallatin’s west side and on the Montana part of the Bitterroot, food and anything that smells has to be in a hard-sided vehicle with the windows closed, in a certified bear-resistant container, or hung 10 feet up and 4 feet out. A fabric tent is none of those.
Check height too. Anything over 10 feet can struggle with the rock overhangs west of Logan Pass on Going-to-the-Sun Road.
A roof tent gets you off the ground and sets up in minutes. It also puts weight on the highest point of the vehicle, and the rack underneath matters as much as the tent. A dealer who installs will check your roof's load ratings before anything else.

How to choose a roof tent
Open it, climb into it and close it before you buy it.
01Know your two roof numbers: the dynamic rating for driving and the static load for camping with people inside. They are different, and the rack has its own.
02Hard shells open fastest and cut through wind. Soft shells give more space for the weight and the money.
03Check the mattress, the ladder angle at your vehicle's height, and whether it closes with bedding inside.
04Ask about parts and repairs before you need them.
05Measure your garage door.
What to have ready before you ask for a quote
The roof decides what is possible.
01Vehicle, and what is on the roof or bed now
02How many people sleep in it
03The weather you camp in
04Garage height, if it lives indoors
05A budget range for the tent and the rack together
Questions people ask
Will a roof tent fit my vehicle?
Almost any vehicle can carry one with the right rack, but check the roof's dynamic load rating in the owner's manual and the rack's rating. The lower number is your limit while driving.
Hard shell or soft shell?
Hard shells are quicker, quieter in wind and better in rain and snow. Soft shells sleep more people for less money and weight, and take longer to pack. If you move camp every day, speed matters more than you expect.
Does a roof tent hurt fuel economy?
Yes, some, and you will hear it on the highway. Lower-profile tents and a fairing help. It is a trade most people accept for the sleep.
