Delaware Memorial Bridge tolls

I recently drove my MH with toad across the Delaware Memorial Bridge on I-95 from New Jersey to Delaware. The toll was $20. A call today to the bridge authority confirmed that if you have a dual-wheel MH with car attached you will be charged the $5 per axle rate rather than the $10 rate for a MH and $4 rate for a car. If you disconnect before the bridge and drive the car separately you pay $14. The difference, $6. Is it worth stopping and disconnecting the car before the bridge and reattaching the car after paying the toll? That's up to you.

By the way, if you leave New Jersey into Pennsylvania via I-78 or I-80 you should be charged the two-axle truck rate and than the car rate, not the four-axle truck rate. Pay cash, E-ZPass will bill you the higher 4-axle rate.
