About the suspension part. Depending on how long you’re really stressing and working your suspension and how fast you’re taking those Forrest roads I’d look into a suspension that has a remote reservoir. Just for the added thermal protection. If you have big money and want an all in one kit Carli suspension makes great kits for F2/350s. They address a lot of issues people have with the trucks and some claim it makes them ride incredible, but SFA says that might not still be close to an IFS truck/SUV.

Get a winch. You may be able to get one for your existing bumper, otherwise you’ll need a new bumper too, but the winch is completely worth it. Those backroads have little to no service and while you can use satellite phones and long range radios in personally someone that likes to rely on myself first. A winch on those roads is perfect. Especially in the snow when you can pull others out, or on the road when you get stuck in mud and can pull yourself out in a pinch.

Tires will be the biggest help. I’d buy either a built in air compressor, or get the ARB compressor in a box so you can air down and air back up when you need to. Lowering your PSI in them tires will make the ride on rough roads more compliant, prevent you from easily getting stuck in mud, and giving you a more sure footed feel. It’s gonna kill your MPG on the road though so airing up after is helpful. Potentially an auxiliary fuel tank or extended tank. Since you’re going off the path and may be out for a long time I always like keeping extra fuel on me for my trips out in remote places.

A good set of Maxtrax would be helpful. The truck weighs a lot so make sure it can handle it, and don’t rely on them, but they’ll work in a pinch. Especially if your truck isn’t 4WD.
