Exploring the internet and checking out tourist board guides, I have found the following driving route suggestions in Belgium. They are not comprehensive and I would welcome additional suggestions.
This first suggestion is from the Rough Guide website.Rough Guide to Belgium
“Belgium’s southern reaches are a striking contrast to the crowded, industrial north, for it’s here in the south that the cities give way to the rugged wilderness landscapes of the Ardennes. Beginning in France, the Ardennes stretches east across Luxembourg and Belgium before continuing on into Germany, covering three Belgian provinces en route – Namur in the west, Luxembourg in the south and Liège in the east. The highest part, lying in the German-speaking east of the country, is the Hautes Fagnes (the High Fens), an expanse of windswept heathland that extends from Eupen to Malmédy. But this is not the Ardennes’ most attractive or popular corner, which lies further west, its limits roughly marked by Dinant, La Roche-en-Ardenne and Bouillon. This region is given character and variety by its river valleys: deep, wooded canyons, at times sublimely and inspiringly beautiful, reaching up to high green peaks. The Ardennes’ cave systems are also a major pull, especially those in the Meuse, Ourthe and Lesse valleys, carved out over the centuries by underground rivers that have cut through and dissolved the limestone hills, leaving stalagmites and stalactites in their wake.
The obvious gateway to the most scenic portion of the Ardennes is Namur, strategically sited at the junction of the Sambre and Meuse rivers, and well worth a visit in its own right. The town’s pride and joy is its massive, mostly nineteenth-century citadel – once one of the mightiest fortresses in Europe – but it also musters a handful of decent museums, some good restaurants and (for the Ardennes) a lively bar scene. From Namur you can follow the Meuse by train down to Dinant, a pleasant – and very popular – journey, before going on to explore the Meuse Valley south of Dinant by boat or taking a canoe up the narrower and wilder River Lesse. From Dinant, routes lead east into the heart of the Ardennes – to workaday Han-sur-Lesse, surrounded by undulating hills riddled with caves, to prettier Rochefort, and to St-Hubert, with its splendid Italianate basilica. The most charming of the towns hereabouts, however, are La Roche-en-Ardenne to the northeast, a rustic, hardy kind of place, pushed in tight against the River Ourthe beneath wooded hills and renowned for its smoked ham and game; and Bouillon, a picturesque little place whose narrow streets trail alongside the River Semois beneath an ancient castle. Bouillon is situated close to the French frontier, on the southern periphery of the Belgian Ardennes and within easy striking distance of some of the region’s most dramatic scenery, along the valley of the Semois.
If you’re visiting the eastern Ardennes, the handiest starting point is big and gritty Liège, an industrial sprawl from where it’s a short hop south to the historic resort of Spa and the picturesque town of Stavelot, with its marvellous carnival. You can use Spa or Stavelot as bases for hiking or canoeing into the surrounding countryside and to venture into the Hautes Fagnes, though the attractive little town of Malmédy is slightly nearer.”

Eastern Belgium is also covered in this guide:
Tourist information for Eastern Belgium:
Belgium, easily accessible from the UK and perfect for a short break, is a land of contrasts. The bustling cosmopolitan city of Brussells, the great port of Antwerp, the medieval gem that is Bruges, are perhaps best known, but Mons, Tournai, Ghent, Liege and Ieper all have something to offer. The flat lands of the north give way to rolling hills and woods which in turn rise to the lovely and unspoilt Ardennes region, perfect for walking cycling and canoeing amongst deep valleys and wooded hilltops. In the far south east is the lovely Duchy of Luxembourg, where the hills of the Ardennes extend to the outskirts of the city, which is well worth visiting in itself.

The Ardennes comprise almost half of Belgium. Beautiful wooded hillsides plunge into deep ravines riddled with caves. Small towns and villages shelter under steep hillsides. Rivers wind their way through undulating countryside. Wonderful walks are everywhere, never difficult but always rewarding. Canoeing, boating and mountain-biking are popular, and cross-country skiing in winter.
Namur is the gateway to the very lovely western Ardennes. The town is dominated by a magnificent citadel – reached by cable car – posesses some good museums, and the narrow streets close to the river house some excellent restaurants and lively bars. Near the town is the Abbaye de Floreffe. Travel by boat from Namur to Dinant, surrounded by steep cliffs and with a citadel of its own. Enjoy the wild scenery of the nearby river Lesse by canoe, or visitRochefort, situated amongst perhaps the most beautiful scenery in the Ardennes with ample opportunity for walking, canoeing and mountain-biking.
La Roche-en-Ardennes is a beautiful and romantic town, topped by a ruined castle and surrounded by hills. Good restaurants and bars make this an excellent base for the wonderful countryside around, where all levels of walking, mountain-biking and canoeing take place. Further southwest isSt Hubert, deep in the forest and an excellent centre for easy walking. Visit the nearby Euro Space Centre and the Parc a Gibier animal park. Bouillon, close to the French border, has a superb castle, an interesting museum, several decent restaurants, and is a great centre for exploring the wild and lovely Semois valley and wooded hills. The forests and hills continue all the way to the border with Luxembourg.
Liege is a large industrial city but is the gateway to the eastern Ardennes, the main town being Stavelot, with pretty streets and an abbey. Here also is Spa, supposedly the first health resort in the world. Further east is theHautes Fagnes, a wild and open heathland plateau.
Luxembourg is more than just its city. The rocky hills of the Ardennes extend into the Duchy, and there are more than 130 chateaux and castles. The scenery is lovely, ranging from the Ardennes to the gentler slopes of the river Moselle in the southeast, flanked with vineyards. Luxembourg city enjoys a spectacular setting, straddling the green gorges of two rivers. Visit the Old Town on the upper plateau and enjoy the sturdy ruins of its fortifications. Descend by elevator or steps to the valley floor. Eat at the many good restaurants and take in the lively clubs and bars.
There are several round trips for bikers that offer good sight-seeing routes too on

There are other websites that give good routes but they are few and far between, especially for motorhomes and campervans.
There is a new publication due out in March 16f called All the Aires Belgium, Holland and Luxembourg that lists the motorhome stopovers.
