If your looking for something to take in your caravan a Honwave 3.5ae ain't the boat for you I'm afraid .
It's much to big and heavy to lug around and carry in a caravan.
Believe me I've tried it
They are a PITA to set up as well - I soon tired setting mine's up and built a trailer for it within the 1st year of ownership.
I'm now using a Honwave t3.8 airfloor for taking in the caravan.
It's lighter and much quicker to set up and goes faster with my 20hp than the 3.5ae does.
The T3.8 t is 48kg all in.
It is awkward to lug in and out of my caravan alone but it is doable.
When I go away with the caravan and my mate we just put our gear in the caravan and in the roof box, fold the back seat in my Tiguan down - Tohatsu 20hp in the boot T3.8 in the back door on top of the folded down seats.
It's a doddle with two adults but a bit of a wrestle when I'm with the wifey and kids with the caravan and sib as I need to man handle it myself.
A lighter airfloor might be a better solution to your dilemma like a Honwave T3.2.
Your Tohatsu 9.8hp should plane it ok.
