Ours drops pressure over the space of a week of inactivity. It's a system with a lot of areas for leaks. I also add air to the pin box after hitching, especially if we have been sitting for a month or so. I rarely have to add any air to it over a week of traveling and same for the suspension. Neither one bleeds down to nothing but they both lose a bit of pressure sitting.

$700 for U bolts seems to be very excessive. They are not kryptonite or gold and are a common use item. I just got a quote for an axle replacement in Tucson and the whole deal was less than $700.00 labor and parts. The quote was because the goodyear shop in Wichita bent the damn thing by jacking the axle next to the spring shackle while changing a tire at an HDT rally. It took some time to show tire wear so I can't go back to them over it, besides it would cost more in fuel to get there than the axle replacement.
