This Brinkley Z 3100 is in like new condition. We added a full solar package system with lithium batteries for extended dry camping. It will easily run a/c while off grid or when pulling over for the night while traveling. Existing solar warranty is transferable to new owner. Add on cost for solar package was ($18,314.00). We also added slide out covers on all of the slides. Both the Brinkley 5th wheel product and Brinkley's commitment to service and attention to detail is absolutely top notch.
