Research by weight?

Thank you for your guidance. We are happy with the Explorer and feel we have many nice options for our needs and comfort. Sound Guy we are looking for a queen bed for us (doesn’t matter configuration) and separate beds for each child (different genders). I don’t wish to make up beds nightly and prefer a bathroom as who wants to take little ones to the bath house at 2 am. I’m not looking for a tow calculator. This is helpful though and I will use it when we narrow the field. I’m really just asking if there is an all in one database to search <3500, 3 beds. I’m guessing not so I will keep driving through the campground writing down names and looking up makes/models/floorplans/weights. Thank you!
