Seal-Rite trailers are the Cadillac of the sealing rigs in my opinion. You get what you pay for, if your thinking about doing this for a while, why not invest a bit more for better equipment that will last longer?
I recommend going to their website or requesting a catalog and you will be able to compared the specs for yourself.
