Mine is 3300# at the axle, empty
so I'd say 3500 pounds minimum, absolutely empty.I bought my H23.5 in Vancouver and towed it over the Rockies to Calgary. I lost a bearing just before going over The Divide. I'd have to say this was due to zero maintenance done to the 7-yr-old trailer by the original owner.Anyway, after replacing the entire axle assembly I drove it over a weigh scale. By this time, the outboard was off the boat, leaving nothing but the battery, a few cheap lifejackets, a blanket, life-ring, and half a bottle of alcohol for the stove. And maybe a gallon or two of gasoline.I have no idea if the new axle is heavier than the factory original.The back axle alone on the scale weighed 3300 pounds. At 10% there would be about 300 more on the hitch.Had I known, I would have gotten a 7000# axle built instead of another 3500 pounder. Had I known I would have made sure the bearings were actually serviced. It turned out in the end the dealer just squirted grease into the Bearing Buddies. I didn't trust the trailer (after reading the reviews here) so I was stopping to inspect the trailer every hour on the road. The last check found the bare spindle riding on the rim. It had ground about 1/3 the way through the spindle. I was probably minutes away from the unthinkable. I was minutes away from spectacular high, windy cliff-edge vistas of the Kicking Horse Pass.Back on topic, I had rented a 3/4-ton diesel to go over the mountains, but around Alberta I have towed the boat on-the-flat with a 1991 Dodge Caravan 3.3L V6. I did add a tranny cooler first. It doesn't seem to labor at all. I am quite sure I'm over the specified towing limit of the van though. Now that it's "at the lake for good" I ony launch and retrive it once a year with the minivan. No problem there....RickM...
