There are MANY threads here discussing the towing weights of 22s and 25s. You may be able to find an exceptionally light weight 25 but mine was 8,700 pounds on the trailer, not fully loaded for cruising (quite a bit of gear in the bed of the truck).
There are also many threads here on what size truck/tow vehicle does one need for that weight. Diesel or gas? You will also get various answers, but for my money, a 3/4 ton diesel pickup is a good match for a 25.
Also for the record, the 25 is a lot more boat than a 22 with an enclosed head. Besides the discussed weight difference, there is more beam, more height, more storage, more amenities (most 25s have a 30 amp electrical system, fridge, water heater, etc). With the 25 being a ton or more heavier than the 25, the ride will also be different.
Both are great boats. Good luck with the decisions.
