2003 lance 1171 and 2017 Srw f350 am I asking for trouble?

This my experience not opinion. We have a 2005 Lance 1121 on a 2004 F-350 diesel 4X4 SRW crew cab LB. We added 19.5" H rated wheels and tires. and have traveled 100.000 miles from coast to coast and from Key West to Alaska with no problems. Weight is around the same maybe a little heavier when fully loaded. The airbags are very helpful leveling fore and aft and side to side. Replaced the tires at 70,000. Will do a second brake rebuild shortly.
