What is the roof load-rating on a 2014 Mitsubishi Challenger?

Most factory roof bar systems are only designed for light duty stuff and will have a maximum capacity of between about 50kg and 100kg. So, by the time you add your 75kg tent plus whatever humans are going to be sleeping in it, you’d be way over the limit and in real danger of collapsing the whole deal onto the car’s roof panel.

Most people who fit roof-top tents or use that real estate to store things like spare tyres, fuel cans and camping gear, opt for an aftermarket roof-rack system which is much better able to cope with higher loads. Try a four-wheel-drive accessories store in the first instance and remember that to make a roof-top tent as safe as possible, you’ll also need to find a ladder that fits the car properly to get in and out safely.

The good news is the Challenger was and is a popular choice for campers, so you should be able to find what you need on the aftermarket.
