alan,
I wouldnt try it.I think the wt w/o power on your tsunami is 3500lbs.with engine(1000lbs)fuel(400 lbs)lbs)and gear(300-500lbs)you're looking at a total wt of about5000-5500lbs.better to err on the side of caution and go with a 6400 or so.if you just need to launch and haul let me know-I have a guy in Bayshore who is so cheap and reliable you may never need a trailer!
hope this helps,
