We just bought a new Sundance 2880 RLT last month and found to our utter shock and surprise that the front compartment has several large (1-2 inch x 15 inch) gaps to the outside that would certainly allow a lot of dust into the compartment, and many of them were large enough to let mice or even squirrels in to have free range of our fifth wheel. We have fixed all of this by cutting and fitting blue styrofoam insulation to fill all gaps and cracks. This is an issue that should have been addressed at the factory.
