I am about to pull the trigger on a very lightly used 2304KS. This will be my first travel trailer purchase. Is there anything I should look for being that this is a used unit? I will be pulling it with a 2014 Ram with the V8 Hemi engine. The trailer dealer is going to set me up with a WDH, sway bar and brake controller. Any tips or thoughts on this set up would be appreciated.
