New to towing vehicle with E-Z Pass question

First set up an ordinary NY E-ZPass account, just as you would for any passenger vehicle. Then go to this link and follow the instructions for the "Thruway Motorhome Discount Plan". There's a link where the needed form can be downloaded and printed out. E-ZPass will send you the proper tag for your motorhome toad combination, and the standard tag gets put in a shielded bag or wrapped in foil while the towing tag is in use.

Very similar to what I have from Massachusetts... I have a transponder for each of my cars (one of which is my towed). I have another one for the MH that is setup for the MH + towed. When I'm towing the Jeep with the MH, the Jeep's transponder goes in the bag (signal blocking) in the Jeep's glove box. I also have an another transponder for the MH for when I use the MH without a towed vehicle. I don't currently have it activated since 99.9% of the time I take the towed, but, if I don't, I activate that one and all of the tolls are correct for the various weights and axles and over-rides any of the "axle counters". It was explained to me, by MA, that mere axle counters may misconstrue my MH and towed combination as a tractor trailer combination (a higher rate), while the transponder transmits the proper MH and towed car combination... It seems to have been working properly so far, I've never had an error in fees deducted. Nice thing about the MA E-ZPass is that there is no charge for any of the transponders, so I have enough of them to cover all of my possible combinations. I had the same setup when I towed a 5th wheel and, again, never had any confusion or issue of incorrect charges.
