you won't be able to tow this because the actual loaded hitch weight is over your van's max.
the 18RBT has a "dry" hitch weight of 336lbs. the max of the minivan is 350lbs. that "dry" weight rating doesn't include the 40lbs. of the battery, the 20lbs. of propane in the single tank and water and cargo.
just adding the battery and propane weight, puts the trailer's hitch weight at nearly 400lbs.(50lbs. over the max of 350lbs.) and that's before you add water and any cargo in the trailer.
the only one that will have a loaded hitch weight under the max of your minivan, is the one canvas end 13FKT.
second issue is what all trailer in the 3500lbs. GVWR class have, POOR cargo carrying capacity.
with a CCC of only 804lbs., this have to account for the battery, propane, water, options and cargo.
a quote from KZ's website:
"UNLOADED VEHICLE WEIGHT (UVW) - The typical weight of this trailer as built at the factory. The UVW does not include cargo, LP gas, fresh water, options or dealer-installed accessories."
these so-called options are the awning, microwave, a/c, oven, spare tire and a few other things. the weights of these come out of the CCC of 804lbs, along with the battery, propane and water also coming out of that.
when it's all said and done, you're likely to only have 200-300lbs. left over for cargo.
you'll be restricted to only the smallest of hybrids with a minivan.
