2021 Tiffin Allegro Red 37 PA, Quiet on the highway, spacious inside, and backed by Tiffin's well-earned reputation for build quality the Allegro Red 37 PA checks a lot of boxes for serious road trippers. The Freightliner chassis with Cummins diesel and Allison transmission is a proven combination that owners consistently praise for ride quality and reliability on long hauls. The **full bath** layout gives you a real bathroom experience on the road, and the generous living area makes extended stays genuinely comfortable rather than just tolerable. At 55,558 miles, this coach has seen some travel but still has plenty of life ahead especially well-maintained on a platform known for longevity. Located at RV Select in Seffner, FL, and priced at $129,900, this is a strong entry point into Tiffin's diesel pusher lineup without paying new-coach prices.
