No aftermarket lift kit? AT4X do but AT4 doesn't come with one do they?
"bed height is right". Does that mean you have a minimum of 5" clearance between box rails and fifth wheel? If more can you raise the Avenue's pin box?
2" @ 20' is <0.5º in any case. (20' is a WAG for distance from 5W axles to pin) I personally wouldn't worry about it. Measure your highest point while hitched on level ground. Under 13'6"? 👍🏼

From the factory, when the 29RL is level, it sits too low for late model HD (3/4 ton and up) trucks. This varies a bit by brand and model of truck but I don’t believe that you’ll find one that sits low enough for the 29RL. Possible solutions (may require a combination of these): raise the pin box as high as proper tailgate clearance will allow, lower the hitch as low as the hitch and tailgate clearance will allow, install lift blocks between the axles and springs, install taller tires and wheels (17 1/2” wheels are one option) or fabricate and install a custom suspension subframe. This is something that Alliance really needs to address. I suspect they designed it this way because the height pairs nicely with a 1/2 ton truck, but I’m not towing it with a 1/2 ton - you do you. I have a 2025 29RL that I tow with a 2026 Chevy 3500HD SRW. I’ve raised the pin box, lowered the hitch and installed 2” lift blocks and it’s still nose high. I’ve decided to live with it at this point
I have a 2024 29RL and it came with 15" tires and wheels (fine print said they could do this) and i pull it with a 2022 2500HD duramax. It also was towing nose high. I bought new tires and wheels in 16" x 235 X 85. seems a bit tall for the trailer but local tire guy worked with me on a couple sizes to try and i've had no issues after 15K miles and it raised the rear so that i don't feel as i will tear the jacks off in every little dip. I also added Sumo Springs not that it will raise the trailer but cushion the ride. Really made a difference in things being relocated in the trailer on travel days. I could lower the hitch another bolt hole but havn"t really seen the need. Good luck!

Another thing to think about is if you raise the trailer, the first step is higher off the ground. After doing the 2” lift, my first step is getting a bit high. If I got taller tires/wheels, I would probably need to change from 3 steps to 4. As you can see, this can get very costly.
