If you live near a DOT scale on the side of the freeway, you can weigh your rig for free if it is not open, otherwise, stay away from it and let teh big rigs go thru! I do this a lot with my rigs just to verify my wts etc. A dump scale will work, as will any other place that has a public scale, landscape supply, gravel pit, moving van/storage places..........
Try to keep the hitch wt to that 10-15% range, I find 17-18% is nice for single axel trailers vs 13-15% for tandems. Max wt depending upon the year of GM you have, is probably 5000/500 dead wt, and 10K/1000HW with a weight distribution. Some newer ones will be 7500/750 or 12500/1250 with a WD system. If you have a titan IV like on my GM dually, you are good to 12500/1250 or 14K/1750 w a WD system. But I have a 2.5" reciever.
Some receivers are good to 10K/1000 like my Torklift hitch on my 96 GM truck, no matter if dead wt or WD setup. As I tow an equipment trailer with 1500-1600 HW< and 10500-11K on the axels with a pintle hitch, so a WD is not applicable, as would a boat trailer with surge brakes.
