What should I do guys?

[1987 Shortwide]

OK, I've been working on my bed a little bit, and I'm getting close to re-assembling it. Originally I was going to do all the body work in there and paint it to match the rest of the truck. Getting into it, it appears that I'll have many hours of work to make it look good under finish paint. There will be a permanent (screwed down) tonneau cover over it, and NOTHING will be hauled in the back. What should I do?

1. Bedliner such as Rhinoliner or Line-X? (I fear the fact of not being able to remove this if I don't like it)

2. Spackle paint (like would be seen in most mid-60's cars...) This would be a cheap alternative to bedliner, cover up minor blemishes, but Im not sure if I can get it in a good non/clashing color.


3. Suck it up and do the bodywork to paint it body color (there has been alot of cutting, piecing together of parts, and welding in the bed, so this is no easy task.

4. Carpet maybe?

I'm really kinda lost with what I want to do under there right now, so lets see some opinions, experiences, and whatever else you guys may think.
