I’d start with just a 7 way plug if you don’t mind losing the “better” charging of the Lance plug. Most auto parts places sell them. You can find the wiring diagrams usually in the package, but if you take your time, you can easily get it set up without the diagram. There are also conversion diagrams for Lance plugs.
As far as swing out brackets are concerned, I don’t think one is better than the other but the hole patterns are different. The ones I bought when going from SRW to DRW are universal which means they work, but are longer than really required.
