A lot of weight indeed. The 26' SeaRay weighed about 9300 lbs total (boat and trailer). Tongue weight was about 500 lbs. The 31' Winnebago Brave had a 11' overhang behind the rear axle. Needless to say, when towing the boat, I didn't keep the RV's water tank (located behind the axle) very full, nor did I allow the kids and wife to ride in the bed back there. But other than that, the Brave was rated to tow up to about 10,000 lbs if I remember rightly. (May have been 12,500....) Actually, you could hardly tell the boat was back there. I also had the V10 for an engine. The pontoon boat before that weighed in about 4300 lbs I believe...guess that's comparable to my C-22 now. When we towed the boat with the Motorhome, we usually had our bicycles with us, so we had those to get around in town or in the campground. If we needed to drive somewhere, we'd just have to unhook and use the Motorhome. But I agree with the earlier comments about if you are going to be somewhere for 3 months, what's a day or two driving separately if you need the car also? Colby
