I always recommend setting up your WD system to handle the trailer when it's FULLY loaded and NEVER at it's empty weight (dry weight). Your DOT safety plate will list the GVWR of your trailer and the spring bars should be a minimum of 15% of that weight (the heaviest your trailer tongue will ever be). Go as close to that weight as possible without being under it. Going too much (too strong) can result in a harsh ride ---
However, according to this web sitethe weight specs for a 2008 Surveyor SV-302 are
Dry Hitch Weight: 811 lb.
Unloaded Vehicle Weight: 5850 lb.
Cargo Carrying Capacity: 3086 lb.
Suggesting the GVWR is: 8936#.
IMO, a realistic loaded weight for the above TT would be around 7500# and a realistic loaded tongue weight would be around 975#. In that case, 1000# WD bars would seem to be a good choice.
OTOH, 15% of the 8936# GVWR is 1340# which, if going with a Reese trunnion WDH, would require 1500# bars.
IMO, using 1500# bars when 1000# bars are sufficient is a good example of where "Going too much (too strong) can result in a harsh ride".
IMO, you can ignore the GVWR unless you actually plan to load to that value. Most people do not. And, most people do not tow with a TW% of 15%.
IMO, a more realistic way to select WD bar rating is to make your best estimate of what the loaded TT weight will be and use 13% of that value for bar rating.
