With a 1,500 lb. tow limit, you want to check things carefully even with 13's. I see Trillium
1300s advertised as being about 1,000 lbs -the factory spec sheet stuck to the inside of a closet door on my '74 Trillium
1300 gives the weight
as 1.500 lbs. The basic trailer - sans fridge
, stove, furnace
, jacks, chock blocks, etc., etc., may well be 1,000 lbs, but as a kayak-building friend once told me, '...everything weighs something', and it quickly adds up.
I like to have about a 50% buffer between the vehicle's rated capacity and trailer weight
- so at a capacity of 1,500 lbs., 1,000 lbs. would be ideal, leaving me some wiggle-room for personal gear and supplies. Adding trailer brakes
would increase that margin to some extent. And I keep the thought in mind that's it not really about how much you can tow, but how much you can stop...
Re comfort - one's person's claustrophobic is another's cozy - a lot depends on the personalities, and on having a plan to ride out the bad weather. E-readers are great - naps work, too. A little transistor radio that tunes CBC1 and shortwave bands can provide a lot of entertainment. Getting out for a while, even in foul weather, can really make one appreciate the warmth and dryness all the more. Like many things, it is whatever you make it...
Good luck in the hunt. For what it's worth, I paid $4,500 for my Trillium
1300 in very good condition - clean, everything working, no damage, no issues. To me, a fair to both sides deal...
