See which dealership has a starter kit they will throw in to sweeten the deal, you can also get them to throw in sway control like the equilizer highly recommended. As you stated all units have problems, it comes with moving a home down a highway, but the memories are priceless. Also the service department will only work the first year you have warranty, you will buy extended years on appliances and such. If something is going to happen its going to be during the first year, so use your unit, dont let it sit the first year and find out on the 366 day something is wrong. Both units will have similar appliances inside. They seem to be the same in most brands. Dometic has the industry covered in that deparment. Are the units four season friendly. I dont think shadow cruiser has four season trailers, that is how they save on weight. Some keystones do though. With those weight trailers you shouldnt have an issue with axles or tires. Look for enclosed underbellies, installed tv, check cabinet drawers to make sure everything is lined up. Other than that, welcome and enjoy your new life.
