Harley's idea is a good one, moving the bikes to an area over the axles. If you have a rear table lowering the table and moving them even further back would also lighten the tongue.
In our 2400 lb Scamp
we try to keep the tongue weight below 200 lbs. We do this by keeping the tongue items few and having a bit of rearward weight.
We keep the tongue light
with only one battery
and one propane
tank. Next year we plan to replace our steel propane tank with a fiberglass tank to further lighten the tongue.
We keep also have a fair amount of rearward weight. We do this three ways.
First we carry about 60 lbs of water. We carry the water because we feel it's comforting and necessary when boondocking
Second we have 5 "beneath the floor" storage containers all mounted behind the axle
. I doubt their contents are more than 15-20 pounds, but again in the correct direction.
Third we have about a 4 cubic foot bumper bon that attaches directly to our bumper. It probably contains 15-20 lbs and is as rearward as it gets. The bumper box contains, hoses, power cords, wooden blocks and a few tools.
All in all this balances the tongue and keeps from overloading the rear of the Honda allowing us to ride level. Though our hitch is rated for 350 lbs the highest rating I've seen for a CRV's ball is 220lbs. Next year we plan to move the ball about 3-4 inches closer to the axle
to further reduce the load on the rear of the Honda, really just because it's easy to do.
