Here's some pictures of the compac 27 cradle and trailer.http://midtechv.com/wp3/?easy-photo-album=compac-27-trailer
The trailer is a 2014 Load Trail with a 22' flatbed + 2' dovetail and full width removable ramp.
Load capacity is 14,000 lbs gross, two 7,000lb axles with electric brakes on both. It can carry roughly 11,000lbs net weight.
I paid $4300 for the trailer with all the options (spare tire, mounting bracket, winch plate, tongue box, extra D rings, full width ramp).
This was a deal because it had some paint flaking off, and no paint warranty. Must have gotten some oil on it before it was painted. A little rustoleum cured that problem.
The cradle came with the boat, I don't know if it was the shipping cradle from Compac, or made later.
I chain the cradle to the trailer with chains and load binders.
I strap up over the boat to the trailer with two 20,000lb capacity load straps.
The truck is a 1999 Chevy 3500 6.5 turbo diesel with 235,000 miles.
I get just at 9mpg when towing the boat. On I75 in the mountains of TN, I'm down to 40mph going uphill on the worst grades.
The problem isn't the going, it's the stopping. but with new brakes on both trailer axles it's not an issue, and I'm way under the trailer capacity.
Legally, you are supposed to have a wide load permit for every state that you travel through if the load is over 8.5 feet wide, which the compac 27 is.
However, you do not need to mark a wide load that's less than 10', nor are you restricted to daylight only driving.
