I agree very hardly. Check everything, slide operation, entertainment system, all gas operated appliances, lights, and remote control for lights (awning).
A few things I found with our RL250:
LP line removed from Ref
Stereo speakers mis-wired
Wire type antenna not deployed
Front and rear entry doors not properly aligned (could see daylight from inside with doors closed)
Slide needed adjustment to close flush
Wall covering in bedroom closet was wrinkled and pulling from trim
TV cable connectors at both entertainment center and bedroom ceiling outlet were either loose or needed to be replaced
A wire cover above at front end of slide for the backlighting was being pulled out from closing the slide (just needed to be trimmed back some- dealer just couldn't handle it so I cut it back)
All have been address either by the dealer or myself with the splendid help from Heartland service/parts depts.
The wife and I love our RL250 now no bugs left.
