You live in Jersey...i would most definetely coat it with a tough bedliner with all the salt and chemicals on the road in that state.
Any of the non DIY Spray on bedliners like Rhino and Line-X will have a rough texture and yes will be hard to keep real pretty,but..they will be the toughest of all and last the longest because of how thick it is,along with a hefty price tag.......
Out of any of the DIY liners,i'd go with Monstaliner for the interior,for one,it's very tough..UV resistant so it won't fade AND you can use a smooth roller and it will lay almost smooth with no pockets for easy cleaning.
I have their color samples and none of it has the rough texture that pocket dirts and water,its more of a fine wavy coating,plus,i can fold the samples in half and it never cracks or peels,very flexible and tough.
I will be putting Monstaliner in my tub when i do the complete tear down and Redo and roll it as smooth as possible...I've coated mine over and over and over with sanding and rattle can paints and it still goes to bare metel in a short time with all the dirt and sand on our feet and under the floor mats i have.
If you never use it off road,you might be OK without a liner as long as you clean the Road salt out in the winter quite often
