For your car hauler I highly recommend the Stromberg Carlson Electric Trailer Jack - Drop Leg - A-Frame - 23" Lift - 5,000 lbs - Black, Item # JET-5000. This is a high-quality jack with a robust 5,000 pound weight capacity. This capacity is much more than what's actually needed for the tongue weight of your 7,000 pound trailer but the healthy safety margin is going to allow the jack to work well under its limit. This will lead to faster operation and a longer lifespan since it won't be under constant stress.

The jack provides a total lift of 23 inches (18 inches from actual travel and 5 inches from the drop leg) and has an outer tube diameter of 2-3/16 inches. I have attached a short video review that you can check out as well.

If you instead wanted to stick with a manual jack I really like the Buyers Products # 3370091265 which features a 5,000 pound weight capacity, 15 inches of travel, and a weather-resistant coating to keep it rust free out in the elements.

Thanks for the photos. You will need to weld on a plate like the Bottom Support Plate for 2-1/4" OD A-Frame Jacks - 5,000 lbs #JSP-100. It sounds like you will need a couple of these plates to create a bracket instead of a reinforcement because…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

Answer 12

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6 inch whereas the 225/75-15 fits widths that are 5 inch to 6-1/2 inch. The 205 is 27.1 inches tall and the 225 is 28.4…
