I have a 2006 32' Bigfoot based on the Kodiak C5500 Duramax Allison platform. It is rated to tow 10,000 lb, and I've towed a 2008 Buick Enclave across country for 3 years now, using a Blue Ox tow bar setup, with no problems. Insurance is around $800/yr. DW can move from cab to coach while underway with no problems. Every rig you can get will have trade offs, pluses and minuses. I wanted a four-season rated rig, and have never regretted my choice, even though I admit to a healthy dose of envy when I see a Renegade Ikon parked a few spots away.... I suggest you spend some time with a good dealer and test drive a few types of rig to find out what you like or don't like.
I just had 4 solar panels installed on my Bigfoot, and upgraded to 6 six-volt batteries, and it works very well. Getting a beefier inverter installed in a couple of weeks, so I'll not need to run my generator to charge batteries very often, only when I need air conditioner or microwave.
You probably already know to check with Toyota regarding towing your truck. Having a trailer to deal with just adds one more thing to trip over when you're camping. Best luck with your hunting.
