I would first see what they are going to spray. I went to walmart and bought 3m ruberized undercoating at about $5/ can and sprayed 10 or so cans under mine. I am sure I was much more meticulous than the dealership could ever be. If I was doing it again, I would spray sound deadening on the underside. They make a product that is sound deadening and an undercoat. I believe you can roll it on or they will sell gun that you can use with a compressor.

When purchasing my 03 F250 7.3, the dealership offered me an option to have a rubberized undercoating sprayed all over the bottom of my truck. They wanted $385 to do this.
Should I have it done or leave it be???
Keeping it really clean will do more than undercoating ,,, a light oil in the doors and fenders helps also ...under coating isn't as nessesary today as it was in the past ...On the very bottom , it may help with stone damage ....385.00 is pretty steep....

I wish I had mine done. I can see small areas of rust starting to develop on the underside of my truck. I do live in the salt belt though. I keep telling myself I am going to pull the bed off and undercoat it, while doing the intake mods. For the OP, you don't have your location stated, so I can't say whether or not you would need it.

May not be environmentally friendly but my dad always heated used motor oil and placed it in garden sprayer. This was 40 years ago. Covered everything under the car/truck, pulled tail lights, fender skirts etc. while wearing coveralls then hit a dusty road in forward and reverse at speeds. May have been better than undercoating as it was thin and went into places something thick might not find. Cheap but effective.
If you decide to undercoat, it is VERY IMPORTANT to properly CLEAN and PREP the underside first. Like a good quality paint job PREPARATION is 9/10 of the job. This also applys to undercoating a used truck.
Really as hard, through question to the person (not the saleman) doing the actual undercoating. Try to visit the undercoating facility, ask to review, in detail the prep stes involved. Also ask to get customers' referrals, names, phone numbers, and contact these customers. This will give you an idea on the quality of undercoating work done on their vehicles.
I know I am sounding anal about this, but I hate to see people thow away good, hard earned cash on a poorly done undercoating job.
I agree keeping your truck clean underneath goes a very long way to prevent rusting. In my opinion nothing will make a truck rust any quicker than mud/salt that doesn't get washed off on a regular basis.
In Canada we have Rust Check and Krown Rust Control, both recommended. Down side they need to be applied every year, also kind of messy when you need to do work on your truck.
The upside they work very well, get into every crevice and corner. It also seeps with time.
I've driven trucks many kilometres on muddy roads.
