Hi, I just purchased a travel Trailer 17' ft box, over all length 21.9 ft. Dry weight 3,405. Should I expect any difficulties. I'm in the 5,000 tow capacity limit. What towing equipment do I need to install to be safe: Hitch, brake controller, etc. Brand names would help. Total passanger weight 335 lbs including dog. Another 275 lbs in additional luggage and bikes. Total weight est. 4,000 lbs.
