WDH have a tongue weight operating specifications for the spring bars. This is not the case where more is better. Sometime the spring specifications are hard to find. But I would stay within the upper and lower specifications or you will have rough ride. For a 2720, which I would expect the loaded tongue weight to be between somewhere in the high 300 and 500 lbs. I would be looking at 600 LB bars. I know the reese 600 bars have a operation specifications for tongue weight between something like 300 to 600 lbs. I would not buy a WDH that the spring bar specifications are outside the tongue weight of the trailer. I bought a 600 for my 2720 and I had a very good 1,000 lb spring bar WDH in my garage. To re-spring a WDH the cost cn be as much or more as buying a new WDH.
