Over a 2 week period, moving 2 hours a day, you would easily cover alot of Ireland. Upon saying that and by the fact thst you're entering through Dublin and leaving by Rosslare, a plan of travelling in an anti clockwise direction makes the most sense. Head northwards around to west and so, on.
At the moment there are two main tourist trails, The wild Altanic Way and Ireland Ancient East in the Republic and Tourism Northern Ireland have a few of their own.
Since I am based in the south, here's a few tips for the south.
Discover ireland is the main tourist information website.
Office of public works, (opw) similar to the uk national trust, are responsible for historic attractions and have a loyalty discount card. After 4 to 5 attractions visits, the rest are free.
I mentioned the motorhome Ireland parking app in a different post.
Like all countries, there are some attractions that are over ran by sheer numbers of people but with a little research, you will find similar, less known spots which are equally impressive. Some places like the ring of Kerry, it may be easier to use a local bus tour company for a day trip than drive the rural roads.
In this tech driven age, we still use a Lonely Planet book as a planning reference for a trip, and can be picked up on amazon, ebay quite cheap.
Lastly, if you are coming over during school holidays, and are booking a couple of commercial campsites, made your booking sooner than later because they do get very busy.
After you have decided a rough plan, ask here and details or recommendations will be fleshed out.
Happy planning,
Malcolm
