Thanks for the inquiry. I am not sure the exact dry weight of my trailer but i did have it weighed fully loaded to travel. The trailer weighed about 2,100 pounds with a tongue weight of about 210. As far as the wood interior goes, the factory would say it adds a bit of weight but in reality i don't think it adds that much. I know someone who has the standard with almost the same options and i think his trailer only weighs 100 - 150 lbs less. Also, i think the wood is more solid ... Not to mention, beautiful. I would think yout Trailblazer would have no trouble towing it. I tow with a 3.0L 6 Subaru Outback.
The Cherokee rally is a get together of fiberglass trailer owners at happy holiday rv park in Cherokee. I believe there are about 23 trailers registered. I am currently spending a few days in Asheville before the rally.
Hope this helps and please let me know if you have any further questions. I may also reduce the price.
