This rig is set up to be off-grid capable the solar + lithium + inverter combo is a serious upgrade that we invested heavily in.

This is a completely turn-key, adventure-ready setup. Everything you need to hit the road just add diesel and groceries!

Buy it for $55,000. Or, packaged with a 2023 Ram 3500 Laramie Dually with 30k miles for $120,000.
