Gaspe is a great trip
If you start in RDL I would recommend Hotel Universel - www.hoteluniverselrdl.com
Nice hotel, good restaurant on site and secure locked parking for truck and trailers. Good night life in RDL also
From RDL you have a few different options on routes and clockwise or counter direction. I would defiantly recommend the 2 interior trails 595 and 597 along with 5 on the north shore Mt Saint Pierre. Snow can be skinny at times on the south east side so a caution in that area if tight on time I would give a thought to skipping this area. (New Richmond to Chandler)
Perce is a great site to see, I enjoy stopping for food but would look to Gaspe for accommodations.
My favorite place to stay is Relas Chic-Chocs. www.villagegrandenaturechic-chocs.com
Great view of the Mountains in the Parc Log cabins with fireplaces and hot tubes.
Mantane is also a great place to stop, good night life and restaurants. Hotel Riotel is a good choice, located directly on the river, with an outdoor spa.

Hope this helps
Also, I wear a mirror on my wrist and have never had an issue. Been riding in QC for 10 years, just have paper work and permit.
