Yeah, good trailers are expensive. I think (and don't remember) that the one under Journey On was $7000, 6 years ago for a 7500# roller trailer. After swallowing the price for a $11,000 engine and 70 grand for the fiberglass shell, I probably wasn't as shocked as you are.
As to the carrying weight, you might want to consider a lower capacity trailer. I did a weight analysis for a 25' C-Dory
here:.
The weight estimate consists of 2 sections. At the top, is the weight where I weighed the trailer with the boat on it, as we were returning from a trip, so it was stocked for cruising, less the kicker and inflatable (which were in the truck.) Gas and water each about 1/2 full. That weight was about 6000#
Second, I did a weight analysis for a floating 25 C-Dory with everything I could think of and that came out to 7000# (subtracting out the 2 ea people from my estimate.).
The factory weights indicate the 26' Venture is ~400# heavier than a 25 C-Dory, so you should be somewhere between 6500# and 7500# when you're towing that boat (boat weight only.)
An 8500# GCW trailer sounds great, but that's more weight to haul around and then when you go to get new tyres, you'll get another sticker shock. The 7500# GCW one makes more sense.
And you might get an estimate on a King trailer from PaulNBriannaLynn above. Sounds like he's involved with them. Then you can compare trailer for trailer costs. Over the years I've learned that a good trailer is a worthwhile thing, because you don't have to worry about the trailer , just the boat. Have you talked with an EZ Loader dealer and see what they're getting for them?
