It is hollow on the inside I have no clue how I can do this, i just want to unwrap the sides and the top and the wheels If anyone can help me please let me know!
Search for "planar-mapping". This is what you need. Just make planar maps for the 2 sides and 1 mapping for the top, front and rear. Then relax everything.
It's $29, dude. I mean, sign up, consume all the UV tutorials and unsubscribe - or better yet, you get a whole month so consume all that you can! It would be a hugely beneficial use of $29.
