Thanks for the grounding information as I did not know this and will look at this on trailers I am looking at. I am looking for a light duty trailer that looks good and tows without issue. I would be very careful not to overload it an expect that 90% of the time I would be putting about 1200lbs on it and doubt I will tow it more than 3000 miles a year, probably a good deal less. I'm towing with a diesel 2500 3/4 ton so the weight of the trailer really is not super important but want a trailer that will last for a lot of years and could be easily towed by a much smaller vehicle.
Thank you for your advise and if there is other things I need to know please do tell.....
