Greetings to everyone.
I am back to report that we have purchased the 28brs, but instead of the Hensley Arrow, I have set it up with the Anderson hitch.
The trailer came at 6000lbs with all the options, batteries and propane, the tongue weight is 700lbs.
The CAT scale is showing everything with in specs.
I have since towed the trailer for 300km in winter highway conditions, driving along semis through snow storms.
I do feel the trucks pushing me if they pass me, but it's a lot better if I pass them.
All in all I am satisfied with the towing experience.
Thanks for all the great info posted here!
