I spent 6 months looking and only bought the Weldbilt because it was new/used hull on a trailer close to home. Imo, there isn't a better commercial jon hull in the market than Alweld. Inspect their welds compared to others.
The factory will build/add a deck and about everything else except an in-floor fuel tank. They will paint it any way you want inside and out, check out the floor non-skid spray, it will stay cool too.
Their website is kind of confusing, you have to pick it over to find the accessories pages. https://www.alweld.com/custom-boats When I upgrade, it will be an 1860 Alweld Marsh with extras.
Call the factory, you'll be happy you talked with the guys there. Where are you located, there is a board sponsor here that keeps a hundred tins on the lot in east NC. Here is one of the deck options.
