Most manufacturers require a WDH for 5000 lbs and above. (Except for those 350 etc) An electric tongue jack is a good investment if you have a problem with cranking the manual jack.
Careful reading of the specifications should tell the tale.
Even the Touareg that I tow with has a dual limit of 5000 lbs with a straight ball hitch and 7700 lbs with a WDH.(this is even though VW says not to use the WDH!).
Even with my 3000 lb
Scamp 16 (modified) I use a Reese Mini 350 and it improves the ride and stability. I bought the hitch when I read the ratings for the Town and Country I was towing with before as the ball limit for the vehicle was 1800 lbs straight ball and 3500 with teh WDH. The hitch helped on that vehicle as well.
If you don't want to use the WDH then don't just realize that you are giving up some safety and comfort margin.
As to using it for just short trips, most long trips are short trips of several hinderd miles joined together!
From Honda:
In your Honda owner’s manual, a table is included outlining how to estimate tongue weight based on rear suspension and compression when loaded or unloaded. There are other alternatives to measuring tongue weight; if you tow frequently, you probably want to measure your tongue weight fast and effectively. Purchasing a tongue weight scale is a compact and easy solution. If you find that your tongue weight either exceeds or does not meet the suggested weight, utilizing load distribution may be necessary to adjust the tongue weight. For larger and heavier trailers, a weight distribution hitch should also be considered.
