Question: how much does it cost to have a horse trailer painted?
Answer: Take it to small, independent shop or a place like Maaco that advertises cheap paint jobs. Should be $400-$500 and will last a good 5+ year. Paying someone to put in bedliner should be around the same so ~$1000 to spruce up your trailer. If you feel adventerous you can buy a compressor, paint gun and paint.
