That Hydra-Lift is nice but you're right...pricey, plus it takes to total weight directly from your GVWR. Your enclosed trailer is best option or buy another smaller trailer just for it. I use my 16' Jeep hauling trailer for our golf cart. A bit overkill but I already have the trailer and we can carry a few other things on it at the same time if we need other stuff. You can get a small 10 or 12 foot flat trailer with a tube rail for around $1,000. Even cheaper for a used one on Craigslist locally.
