If you buy a new one depending on if its a 2016 or a 2015 they all make the dealer money. Let's use a figure of $150,000 MSRP as a standard.
I have found that in reality you buy it at that price you lose $30,000 -$40,000 when
you drive it off the lot.
With any large dealer with a good service center you should be able to buy the above $150,000 rig for $110,000 - $120,000.
The older 2015's should be a better deal and get closer to $100,000
One note... Never buy the extended warranty but save the $2,000 in your bank account.
Now if you are watching your dollars and want to save but a used rig that is 1 or 2 years old with low mileage. The Ford engine and chassis is solid and don't have many issues as I have had my 2012 now with 40,000 plus miles on it and have my AC compressor replaced and a sway bar bracket replaced by Ford under warranty.
If you buy used
even if it has come cosmetic issues is not a deal breaker. The amount of money you save will easily off set that.
Now I would look around for a good rig with an interior I like. Bed size is the only thing that matters to me and all the rest, appliances, floor, cabinets, lights are mostly the same in all rigs.
Depending on how you plan on using your rig full time, part time, or just local casual use you may think about other things like type of flooring, electric fire place, Getting the Georgetown XL model instead of the plain jane Georgetown.
The XL has many extras that is worth finding one. Exterior paint with clear coat and not stencils, exterior access door and locks different, double pane windows, electric front shade, and a few other things like convection oven instead of just a microwave oven.
Now if you have basic mechanical abilities the used one would same you lots of dollars and gain the enjoyment of taking care of your rig yourself.
Price for a 2 or 3 year old model with low mileage (2,000- 3,000) and good condition should range between $85,000 and $90,000 which is a good savings.
If you have cash you can find great deals on Craigslist to see what the used prices are in your area. Sometime people buy and find out it takes time and money to run one of theses and try to sell them after a few years. That is why I like watching Craigslist for good deals.
Now you found new or used to buy.
You need to full test , examine and dealer or owner to show you how everything works before you do the final cash transfer. You will read here about folks having rigs years and not knowing the basics about their rigs. Coach battery location and condition, location and use of all the water lines and valves, what you need to do prior to winter in cold areas.
If you have a friend that you trust have them take a close examination of the rig as if he/she was buying it. If you find anything that seems to be costly this can help you negotiate the final price. Such things as irregular worn front tire which may need a frontend alignment and new tires. Leaking hydraulic system for levelers and slides, oil leaks on engine, old oil in engine, these things need to be addresses before you buy. See if you have a local RV repair shop that will inspect the rig for you for $100 and give you a report.
Now if you buy new make sure you during the PDI is in writing and don't grab the rig and leave to find out the issues. I left my motorhome at the dealer to take care of all issues before I drove it off. They want it off the lot so they take care of things quicker.
Don't get me wrong about buying your motorhome. It is a great way to enjoy life, family and see great new places. All you need is the money, time wanting to enjoy the travel.
Hope this short message will help you make your final decision in your selection.
