Congrats on the new Marlin.
Recommend you ask the dealer exactly what they intend to provide for your ground tackle. My experience is that it is often at the "minimal" end of the range for both anchor type, size, and length of both chain and rode. While those selections depend a lot on what types of bottom and the depth of water you expect to anchor in, your should be looking for chain equal to the length of the boat, an anchor at least one size larger than what is recommended on the web site for that anchor manufacturer, and 300-feet of rode.
If you have a windlass, then I strongly recommend you get plaited line for your rode, instead of 3-strand.
If the dealer isn't happy with this level of ground tackle, then negotiate as needed, but no sense in starting off with the usual off-brand of "Danforth-type" anchor, 6-ft of vinyl covered chain, and 150-ft of 3-strand nylon.
I hope you are pleasantly surprised when you ask the dealer about the ground tackle, and find that they were already set to "do it the right way".
(Then ask what kind of life jackets they are providing)..
