To make it clear this is no High end product it is cheap. This was a gift so I took it to the bike room and gave it a go.
Priced at 79.00 , here is what I think. rated at 1250 pounds.
This came to me as a gift. It is a Dolly not a lift. It took about 15 minutes to assemble . I first put the Fat boy on it. the bike fit on length wise . It seems the area for the Jiffy stand was right at the limits but it worked. The Bike went on with ease and was stable. I was able to move the bike any where I wanted with little effort.
Riding off it was effortless.
Next the RGU. Riding on it was no problem and the Dolly was stable The lift is about a inch or two shorter than it could be but the bike fits. The locks or stops flip up and down they hold dolly in place and form a slight ramp to ride on and off. When you raise them it is a tight fit with the touring bike. But manageable and stable.
I was again able to move the bike any where I wanted with low effort and the dolly was stable at all times.
I have already started looking at ways to mod the dolly a bit to better fit my needs but that just goes with being a HD rider , we mod anything just because we can.
End result The Haul master is a cheap Dolly that works not for everyone but if you need to roll the bike around it may be what your looking for. It surely will not last 20 years of heavy use but should serve many well.
