I have a new to me 2004 Bunkhouse LX. In trying to calculate the proper tongue weight I had the trailer weighed. Much to my surprise, with the 80 pounds of gear I'd added it came in at 572 pounds which is at least a 100 more than I figured. The manufacturers label states the GVRW is 500 lbs. For those of you who tow these is 572 a reasonable or safe weight to tow this at with a GL1800? Manufacturers web site states this model weighs 342 pounds - anybody know what they might have included in that? I have a tongue weight of 52 pounds - is this ok? Any thoughts or advice appreciated.
