Different years, same model, can be Tag or Non Tag... And Used vs New, fine you said both... But how far back? And gas vs diesel (As some gassers had a trailing tag too
!)...
But, some coaches with tags at 40', at various years, include:
-Alpine
-American Coach
-Beaver's Patriots Thunder, Marquis
-Wanderlodge
-Prevost confessions
-Country Coaches (Allure/Intrigue/Magna/Affinity)
-Monaco - Dynasty/Executive/Signature (And Holiday Rambler equivalent.)
-Tiffen Allegro Bus/Zephyr
-Newmar - Dutch Star/Executive/London Aire (not sure on the higher food chain, if they had 40' with Tag...)
-Foretravel - U320/Phoenix/Nimbus (U295? and others?)
-Tripple E Empress (MAY have had one Tag coach?)
-Winnebago/Itasca ....
-...... Others...
And I know many, many more...
Suggest you narrow down your price point, and age of coach considered. And more definitive answers would be available...
Good luck on your research,
