Ok, got her all weighed. 13,100 even with me, one teenager and the toddler. Figure I will pull out the pots and pans and a 27 inch flatscreen and some camping stuff - say 50 lbs. So one more adult male at 170, women at 125, 145 and 105, two more young teenagers at 90 each. So that puts me at 13,775 plus tongue weight of 315 so 14,090. Leaves me with 410 for luggage and skis.
The van and trailer are at 5,110 already. But I'm thinking I will put the skis in the mini van and the luggage in the RV cargo compartment. A typical clothing bag at the airport when we travel is about 40 lbs which usually includes one adult and one kid, so another 200 lbs. Put's me about 200 lbs under in the RV (a slight margin of error) but including skis about 200 lbs over in the tow vehicle.
I've pulled this van on a lighter tow dolly before and I can't even tell its back there performance wise. And this new dolly is much more solid and has trailer brakes which will be nice.
Does this seem doable? Unfortunately this has to be determined on the theoretical level, because if we decide to load this rig there won't be any going back.
And as far as the comfort goes, the alternative for these kids is to be strapped into a really crowded mini van for 20 hours, so while this conversation is still theoretical, if it can't be made to work then that is the alternative.
Thanks again for indulging me.
