Symptoms of a heart attack should prompt one to inform other people in the area that such symptoms are occurring. You should not attempt to drive, or even have someone else drive you to the hospital, but simply call 9-1-1 or the emergency services in your location immediately.
Well Phillip, my neighbor had a very similar houseboat and it weighed @ 11-12,000 pounds. It was a 33 foot Nautaline Houseboat, however a 1970, which shouldn't make a difference. Lastly, hopefully some of our readers and visitors will share and post comments about their houseboat trailer and weight experiences.
Dry weight of the boat was 2200 lbs. Motor, fuel and 'stuff' pushed the weight to about 3000. My tandem axle Shoreland'r trailer weighed 1200 lbs. No experience with an Xterra, tho- I was driving a 1/2 ton pickup.
