The caster will swivel to allow easy movement for that application. If the caster needs to be kicked it is possible the 800 pound load capacity is being exceeded.

Is it easier to move a loaded boat trailer with the caster? A lot easier? Or do you have to constantly "kick" the wheel in place?
We have to kick the regular boat trailer in place all the time when we're trying to guide it into the garage or carport. So, would it be better to get a dolly without the caster? Thanks!

Having the run flat tires I assume they are a solid type. How does this effect the maneuverability over grass,rocks or other obstacles?
-
UltraTowExpert11· 3 years ago
The dolly will come with flat-free tires. A flat free tire will have less give and cushion when running over rocks etc. than a pneumatic tire.

They are plenty hard to go over anything. However, the foam in my tires broke down after about 3 years and required replacing.

My trailer has a pintle lunette. The ball doesn't appear removable; there is no accessible nut. Does this product have a pintle hitch connector that we can replace the ball with? Thanks
1 answer-
UltraTowExpert29· 6 years ago
The hitch ball on this dolly is removable. The adjustable tube is threaded to fit the hitch ball. This dolly does not have a pintle hitch connector available.
