Thinking of buying a 2019 Jayco Eagle HT 28.5RSTS

If this is from a dealer, they are taking 25% off. You could approach this in a different way. You said you don't have a hitch (check your PM box), so you could counter the dealer with 42,000 and they throw in a Reese 4 way swivel head hitch and rails. Rule of thumb is 25-30% off MSRP.
