I'm looking at buying bumper pull trailer to haul around my Jeep and my '49 Chevy Truck (not at the same time). I am looking at either a trailer rated at 7000 lb or 10000 lb. The Jeep only weighs 4500 lb, but I know the truck is considerably heavier. Will a 7000 lb trailer stand up to years of towing or should I step up to the 10,000 lb trailer? I am also looking to spend as little money as possible, will don't mind paying more for a heavy duty item if needed. Thanks for any help guys.
