2011 Heartland Heartland 277 RL, THE PERFECT CHOICE FOR 1/2 TON TRUCK OWNERS! The XLT ultra lightweight line of towables is quite possibly the strongest built lightweight series ever to hit the market! Featuring all-aluminum, fully laminated construction - including the laminated roof - the XLT is built to stand the test of time. The XLT fifth wheels also feature Heartland s Patent Pending Improved Turning Radius cap design that allows you to turn up to 88-degrees in most short bed, extended cab trucks! Every SUNDANCE XLT owner will enjoy their vacation a little more because of the attention to detail Heartland pays to every aspect of the SUNDANCE XLT from construction methods to thoughtful use of space and everything in between
