Hi neal,
Welcome to the Heartland Owners Forum. There's lots of useful information here along with a great bunch of friendly and helpful people.
You've got a good list of detailed questions. I'm sure other owners can answer most of the questions, and the Landmark Brand Manager may also respond. But sometimes the best thing to do is to Heartland Customer Service at 877-262-8032. Identify yourself as a prospective customer and ask to speak with the Landmark Brand Manager.
Can a Landmark be purchased direct from Heartland without going thru a dealer? I'm pretty sure it's dealers only.
I noticed Heartland provides a means for aligning the axles-- are the axles aligned properly at the factory? The axles are built to spec and assembled by the axle manufacturer. They mount to hangers that are welded in place by the frame manufacturer. All that to say that alignment of new parts is not done, IMHO is not necessary, and as has recently been discussed here, there seems to be no evidence from owners that would indicate that it would be necessary. The Correct Track feature allows corrections to be made after hitting potholes, curbs, etc.
Does Heartland allow for selection of TV's and audio equipment. You could ask the Brand Manager, but I'd guess that might be something left to a dealer or to you.
What are the warranties for a Landmark-- and can an independent RV repair shop be reimbursed? As I recall, Landmarks have a 2 year/5year warranty as explained in the product brochures you can download from the Heartlandrvs.com website. Independent shops can be used with prior approval from Heartland.
How does Heartland mount/install the washer dryer? Location depends on model, but I believe the general approach is a stacked Splendide configuration that vents through the outer wall. If you get full-body paint, you'll want factory install so that the vent is also painted. There's an overflow tray under the washer that drains to the outside in case of malfunction.
What equipment is included in the full timers package? Bike receiver hitch, Surge Protector, Tire Pressure Monitoring System. Generator prep option is a pre-req for this.
Does the buyer have selection of surge-suppressor? I don't think so. I believe the surge protection may be integrated into the transfer switch that comes with the generator prep.
Can two 100 watt solar panels be factory installed? You should ask the Brand Manager, but I've not heard of this being done.
