Lack of maintenance, small wheels or not, it doesn't matter at this point. I'm done with this. I bought this trailer because that was all I could afford, but considering the total cost of the trailer--$580+--, I would have been far better off buying a better trailer. Add in the cost of making all those upgrades, and it would have been cheaper to buy a better quality product.
I had not had much experience with Harbor Freight at the time I bought this. If this series videos helps other o make a better decision--better tire, bearings, bunks, or just deciding to buy a different trailer altogether, then the video has accomplished it purpose.
