Overall length

so I’m concerned that the truck won’t fit into my garage. I live on a hill and I am a paraplegic. So loading and unloading my wheelchair is not smart to do on a hill. Learned that one day the hard way. But what is the overall length of the truck. It’s a 5.5 bed and no I cannot go measure it. It’s inside a shop getting outfitted with controls for me since I obviously cannot use the brake and gas. I know I’m new here so please don’t haze me to much. I have googled the length and all I could find was wheelbase.

Also, is the crawl features and all the off road stuff easily accessible to do? I’ll post a picture of my tuck. That way I don’t get a bunch of questions.

Finally, what is the little piece of bumper under the drivers side rear bumper of my truck. I’ll try to up load a picture of it circled

Thanks everyone airbornefister out!
