We owned a Lance 992 for two years and did a fair amount of traveling with it.
We went up the Alaska Highway, crossed Canada from BC into Ontario.
Our truck is a Dodge Diesel, one ton dually. When we put the 992 on the truck we attached the old style turnbuckle tie downs after we put belly bars under the truck. No air bags or any other suspension gadgets.
It worked fine for us. No problems.
At one trip the computer on the truck died and we were pulled behind a tow truck from Dease Lake on the Cassiar Highway to Smithers BC, a distance of about 800 km.
The camper never moved one hair during this towing trip:
At the Dodge dealer in Smithers, British Columbia.
The reason we sold the 992 is because my wife was disappointed with the storage space. We recently bought a new Northern Lite SE, which has way more storage space, but of course no slide outs.
Other than that we think the Lance 992 is a great camper, we liked the quality workmanship.
