I've had many trucks and never wanted a cap for ease of loading big and heavy things. Now we have a travel trailer and I'm considering one, both for towing aerodynamics, and to cover things that ultimately end up in the bed when traveling. So I want something that's easy to remove. Today I went to a ARE dealer near by and the first thing that strikes me is that they want to wire lights in the cap and a high brake light. That is going to hamper removal, not to mention I'm not a fan of them messing with my trucks wiring. So what do people think? I thought about the soft caps, but I don't think they are going to help aero much. Thoughts?
