I'm "reading between the lines" with this post, so it may or may not apply to the OP's question. In the first post, you indicated you're looking to buy a Cougar XLite 33MLS. In your signature, your tow vehicle is listed as a 2010 GMC Sierra 5.3 ( I'd guess a half ton model???). The specs on the Keystone RV website specs for the 33MLS are:
Shipping Weight 7675
Carrying Capacity 1875 (GVW 9550)
Hitch 750
Length 36' 5"
Height 11' 4"

That's a very large trailer for a half ton truck, and if you look carefully at the specs, you'll see that the empty trailer tongue weight as listed is only at 9.77% of the empty weight. The recommended tongue weight for all trailers is 10-15%, so the posted "at first glance" tongue weight can be very misleading.

By the time you load the trailer, add the weight of the hitch and put a battery/propane in the mix, you're going to be looking at a tongue weight of well over 1000 pounds.

So, my question to you would be: Are you planning to also get a larger tow vehicle? If not, you may be buying more travel trailer than you can safely tow with your current truck.
