Welcome you may wish to contact ETI an find folks nearby you that will show you their trailer go look,sit etc see which size you would like .Before that though , check the vehicle you wish to use for a tug find out what it's capacity is for towing and tongue weight that it can safely handle as that may dictate which trailer you can tow.
As you are in Abbotsford you are very close to ETI's facility. You should take a run over there and take a look at what they offer. If you can tow a 5th wheel, take a look at the 5er offered by GerriJ on this forum. I was hoping to buy it, but alas circumstances did not permit it. It is kept under cover and is in perfect factory condition- a beautiful unit.
