recommended travel trailer toy hauler

Is that <40' truck + RV length? Then you are likely in the 18' box length which is a very small TH. If 40' is just the trailer length, then you will likely be very limited for payload in the truck. TH have very high % of tongue weight, so 6000 pounds dry means 7000 pounds loaded without the toys and probably 1100 pounds of TW. I highly recommend upgrading to a 3/4 ton pickup if you stay with bumper pull RV, or 1-ton if you want a fifth wheel RV.

How do you plan to run AC in the TH at these games? Are there others who do what you want to do?
